تعريف mass number في الإنجليزية الإنجليزية القاموس.: The total number of protons and neutrons in an atomic nucleus; 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; (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; the sum of the protons and neutrons that make up that nucleus (or sum of nucleons); (1) The sum of the number of protons and neutrons in the nucleus of an atom (2) The integer nearest to the atomic mass; The number of protons plus the number of neutrons in a nucleus; approximately proportional to its atomic mass; The total number of protons and neutrons in the nucleus: A=Z+N This is also the total nucleon number of the nucleus; Total number of neutrons and protons in the nucleus of an atom Approximate measure of the mass of an atom Also see atomic number; The sum of the numbers of protons and neutrons in an atom; an integer; (A) the total number of protons and neutrons in the nucleus of an atom #p + #n; The number of neutrons and protons in a nucleus
