mass number
the total number of protons and neutrons in an atom
Mass number is the average number of nucleons found in a large sample of an element Naturally occurring chlorine exists in the form of two isotopes Cl37 (25%) and Cl35 (75%) Therefore the 'average' mass of a chlorine atom is 35 5 Chemists use mass number because they deal with large quantities of atoms Physicists prefer the term nucleon number and deal with individual isotopes rather than the naturally occurring mixture of them
The sum of the number of neutrons and protons in an atomic nucleus. Also called nucleon number
The number of protons and neutrons in the nucleus of an atom
total number of protons and neutrons in an atomic nucleus
the sum of the number of neutrons and protons in an atomic nucleus
The number of nucleons (protons and neutrons) in the nucleus of an atom
the sum of the number of neutrons and protons in the nucleus of an atom
the total number of protons and neutrons in an atomic nucleus
(1) the whole number closest to the atomic mass of an atom (2) the sum of the number of protons and neutrons in the nucleus of an atom
the total number of protons and neutrons in the atomic nucleus of an atom
The number of protons and neutrons in an atom
The total number of protons and neutrons in an atom or ion
Mass number (A) is a characteristic property of a specific isotope of an element, equal to the sum of the number of protons and neutrons in the nucleus
The whole number nearest the value of the atomic mass of an element as expressed in atomic mass units
total number of protons and neutrons in a nucleus
