The simplest way to do this is to find a Periodic Table which shows the mass of the atom, (the best choice is to find one which doesn't use relative Atomic Mass, have decimals), and take away the proton number, (it will be to bigger number take away the smaller number). This is because the mass of the atom takes into account usually only the protons and the neutrons. Therefore, if you take away the proton number, you are left with the mass of the neutrons.

What makes an atom And what makes what makes an atom Their has to be something that makes that and something that makes that Is it an on going process?
An atom is made of nuetrons, nutrino, anti neutrino, protons, electrons, positron, a nuecleus, and an electron cloud. They are all made from objects that are in you besides atoms.
Atomic number of an atom is equal to the number of?
The atomic number of an atom is the number of protons in that atom. For example, the atomic number of hydrogen is 1 because one hydrogen atom have one proton.
An element is determined by the number of?
An element can be identified by the number of protons in the nucleus of its atoms.
Do nuetrons have negative charge?
no neutrons are neutral.
What does the atomic number tells you?
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
How do you calculate the number of nuetrons fo an atom?
You cannot calculate but you can guess mostly by its atomic number. Studies shows that while carbon atoms mostly have 6, some are 5 or 7.
How do you calculate a mass of am atom?
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
What is the sum of the number of protons and the number nuetrons in an atom?
mass number
What is the sum number of protons and nuetrons in the nucleas of a atom?
The Mass Number.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
How do you determine the number of nuetrons in an atom?
Number of Neutrons = Mass number - Atomic Number
A form of an atom which has a changed number of nuetrons i call what?
Isotope.
How many nuetrons are in an atom of magnesium?
there are 12 nuetrons in an atom of magnesium
How many nuetrons are in phosphorus atom?
there are 16 nuetrons in phosphorus atom
What information must be known in order to calculate the mass number if an atom?
The mass number = the number of protons + the number of nuetrons. Each of these particles is considered to have a mass of 1 amu. (atomic mass unit) For example, Aluminum has 13 protons and 14 nuetrons, so it's mass number = 27.
What is the number of nuetrons in a potassium atom?
The most common isotope is 20
What is the total number protons and neutrons in an atom called?
mass number = protons + nuetrons
