QuestionHow can I find the electron and proton numbers of actinium?Meredith Juncker is a PhD candidate in Biochemistry and Molecular Biology at Louisiana State University Health Sciences Center. Her studies are focused on proteins and neurodegenerative diseases.You will find actinium in group 3, period 7 of the periodic table. The atomic number of actinium is 89, which means there are 89 protons. Because there is no net charge, we know that # protons = # electrons, so there are 89 electrons as well.

QuestionHow do I find the number of protons are in a nucleus when given the atomic mass?Community AnswerAll the protons are present in the nucleus, or centre of an atom. You need the atomic number to find the amount of protons and/or electrons, unless you have the amount of neutrons and the atomic mass, in which case you can simply subtract the amount of neutrons from the atomic mass, leaving the amount of protons in the atom. The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together. Whichever you know, you subtract from the atomic mass.

QuestionIf element x has 102 protons, how many electrons does it have?Community AnswerThe number of electrons in an element is the same as the number of protons.
-
QuestionWhat is the difference between a group and a period?Community AnswerA group is the elements in a vertical column of the periodic table. A period is all the elements contained in a horizontal row.
-
QuestionWhat are valence electrons?Community AnswerValance electrons are the electrons in the outermost layer of the Bohr model of an atom.
-
QuestionHow can I find the number of neutrons by an atomic number?Community AnswerThe number of neutrons can be found simply by identifying the atomic mass (found at the bottom of the element on the periodic table) and the atomic number. Subtract the atomic number from the atomic mass. Remember that the given atomic mass has to be rounded off to the nearest whole number before any further calculations.
-
QuestionWhat's the differences between electrons, protons, and neutrons?Community AnswerProtons are positively charged, electrons are negatively charged, and neutrons have no (neutral) charge.
-
QuestionHow do I calculate the electron, proton and neutron?Community AnswerThe atomic number is the proton. The number of electrons in an atom is always the same as the number of protons in the nucleus, unless it is an isotope. The neutron is the atomic mass minus the atomic number.
-
QuestionWhat is the charge of 5 protons and 6 electrons?Community AnswerFive protons and 6 electrons would give an atom a negative charge, as the number of electrons are more than the protons, and electrons are negative.
-
QuestionHow do I round the atomic mass?Community AnswerRounding the atomic mass will be the same as rounding any decimal number. If the digit is less than 5, keep the digit before it the same (e.g., 0.44 becomes 0.4). If the digit is 5 or greater, round the previous digit up (e.g., 0.45 becomes 0.5).

QuestionWhat is an element, mixture, compound and atom?Community AnswerAn element is a substance that is made up of one type of atom. When two or more elements are joined together, molecules, compounds and complexes are obtained. Before we understand what a mixture is, we need to know what a pure substance is. A pure substance is one that is composed of only one type of particle -- examples include oxygen, gold and others. A mixture is a type of substance in which two or more pure substances are mixed but are not chemically combined (i.e. chemical reactions do not occur). A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. An atom is the smallest component of an element, characterized by a sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons.
-
QuestionWhich element has same number of electrons, protons and neutrons?Community AnswerCarbon-12. Carbon-12 has a mass of 12 and an atomic number of six, hence the number of neutrons = 6 because 12-6=6. There are 6 protons because the atomic number is 6, and 6 electrons because the # protons = # electrons.
-
QuestionIf protons is given, how do I find the neutrons?Community AnswerProtons + Neutrons = Mass number. Therefore, obtain the mass of the atom and subtract the number of protons from it to get the number of neutrons.
-
QuestionHow do I calculate an electron or find the number of electrons?Community AnswerFind the atomic number. The atomic number is the number of protons (the positive charge) and therefore electrons (the negative charge).
-
QuestionCan there be a different atomic number and atomic weight?Community AnswerYes. Very few have the same. It all depends on the element.
-
QuestionHow do I determine the number of electrons in an atom?Community AnswerIn atoms, the number of protons and the atomic number are equal to the number of electrons.
-
QuestionIs there an easier way to find how many neutrons there are in an element?Community AnswerIf you subtract atomic mass with the proton number of the element, you should get your neutron count.
-
QuestionHow do I know if an element is in a neutral state?Community AnswerIf you mean if the atom of an element is not charged, then the number of electrons should be the same number as the atomic number of the element. If you mean that the element is non-reactive, then the valence electrons of the atom of the element should either be 2 or 8 (this implies that the atom is stable).
-
QuestionHow do I determine how many electron are in a He atom?Community AnswerThe number of electrons in an atom equals the atomic number. The A.M of Helium = 2, therefore electrons = 2. However, if you are talking about a charged helium particle, the electrons will differ. The charge of a helium particle = 2+. This implies that a helium ion lost two electrons; therefore, the present number of electrons will be obtained by subtracting the charge from the atomic number, i.e, 2-2 = nil.
-
QuestionHow many particles are in the nucleus of an atom of Americium?Community AnswerThere would be 95 protons and 148 neutrons, so there would be 243 particles total.
-
QuestionHow can I find the number of electrons in an uncharged atom?Community AnswerThe number of electrons is equal to the number of protons in an uncharged atom. The number of protons is equal to the atomic number, which is written above the element on the periodic table.
-
QuestionWhat is the difference between the mass number and the atomic mass?Community AnswerThe mass number equals the number of protons and neutrons together. The atomic mass is the average mass of all the isotopes of a certain type.
-
QuestionDo electrons have the same mass as neutrons?Community AnswerNo, the relative mass of an electron is 1/1840 the mass of a neutron.
-
QuestionWhat the difference between a double and single bond?Community AnswerOn a structural model, the difference between a single and double bond is the amount of outer electrons that are shared. For instance, Ethylene (C2H4) forms double bonds easily. Although the hydrogen forms single bonds and only forms a pair to the carbon, the carbon itself will bond to the other carbon and form four shared electrons. When written, the four shared electrons are counted in pairs, thus being two pairs or a double bond. It is best explained when illustrated, but in simple terms, a single bond has two shared electrons forming one pair, while a double bond has four shared electrons and forms four pairs.
-
QuestionHow do I find the atomic number?Community AnswerThe atomic number is located above the element symbol in the periodic table, in the upper left-hand corner of the square. If you know the number of protons of the element, you can find the atomic number because they are the same.
-
QuestionHow can we calculate valency?Community AnswerThe valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of electrons, you can easily calculate the valency.
-
QuestionAre electrons, protons, and atomic number all the same?QUINTIN FILES (Student)Community AnswerYes. The amount of protons is equal to the atomic number, the number of electrons is equal to the atomic number, neutrons is the only difference. Neutrons are calculated by taking the atomic weight (or mass) and subtracting it from the atomic number. If the atomic number is smaller, subtract the atomic number from the mass.
-
QuestionHow do I find the number of neutrons if only the atomic number is given?Community AnswerYou can't. You must have the atomic mass to find the amount of neutrons. Atomic mass - atomic number = amount of neutrons. The atomic mass can be found on a periodic table, usually under the element's symbol.
