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!!! :)
The mass number is equal to the number of protons plus neutrons. The mass number is located below the element name on the periodic table.
the mass number is number of protons in an atom, plus the number of neutrons.
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
Argon has a mass number of 40
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
Mass number!:)
The specified atom can not exist, because the mass number of any atom must be at least as large as its atomic number!
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 number of neutrons in an atom can affect the atomic mass of an 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 mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
mass no - atomic no = number of neutrons in an 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 atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
