Atomic Mass: protons AND neutrons
atomic number: just protons
The mass number of an atom is determined by counting the total number of protons and neutrons in its nucleus. Electrons, which are much lighter than protons and neutrons, are not included in the mass number calculation.
mass number= no. of protons + no. of neutron
The Number Of Protons & Neutrons In An Atom.
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
Number of Neutrons = Mass number - Atomic Number
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
no --- atomic number
Essentially an atom's mass is determined by its number of protons and neutrons, as mass of electrons is so minuscule relative the nucleus.
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
The mass number of an atom represents the total number of protons and neutrons in the atom's nucleus. It is used to determine the atom's mass, which is important for understanding its properties and behavior in chemical reactions.
