You can't change the mass number of an atom because the mass number is the number of protons which is the atom's atomic number
I hope this helped :)
because when mass number will change then the whole atom will change.
The atomic mass of an atom can be changed by adding or removing subatomic particles. By adding or removing protons, neutrons, or electrons, the atomic mass will be altered. Changing the number of protons will change the element, while changing the number of neutrons will create isotopes of the same element.
Mass number!:)
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.
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
The number of neutrons in an atom can affect the atomic mass of an atom.
A transmutation reaction always involves a change in the identity of the atoms involved, resulting in the formation of different elements. This can be achieved through processes like radioactive decay or nuclear fusion.
the mass number is number of protons in an atom, plus the number of neutrons.
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
The mass number of an element is the sum of the number of protons and neutrons in the nucleus of an atom. For an atom with a mass number of 15.9994, it indicates the average atomic mass of an oxygen atom.
