in order to obtain the mass number of an atom you must get the number of neutrons + the number of protons which = the mass number !!!
hope this helped!!! :)
Mass number!:)
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.
Fluorine is a non metal element. Mass number of it is 19.
nucleons
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
The mass number of an atom is obtained by totaling the number of protons and neutrons.
atomic number is the total number of protons OR electrons in an atom. mass number is the total sum of number of protons and neutrons. atomic number subtracted from mass number gives the number of neutrons in an atom. Mass number - atomic number = number of neutrons.
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.

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 :)

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.
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.
