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 of an atom is obtain by totaling the number of what?

The mass number of an atom is obtained by totaling the number of protons and neutrons.


Would you use atomic number or mass number or both to obtain the number of particles in an atom?

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.


The sum of the protons and the neutrons indicates the .?

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.


What is the mass number of a atom?

the mass number is number of protons in an atom, plus the number of neutrons.


What do you get when you change the mass number of an atom?

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 :)

What is the number of neutrons in an atom affects the atomic what?

The number of neutrons in an atom can affect the atomic mass of an atom.


Is atomic number the same as mass number?

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).


What does the mass number of an atom tell you about the atom?

The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.


What do you get if you subtract the atomic number from the mass number for a particular atom?

mass no - atomic no = number of neutrons in an atom.


Why atomic mass is different from the mass numbers?

atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom


What does the atomic mass number of an atom tell you about the atom?

The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
