Number of Neutrons - An Atom determines an Element
The purest type of atom is called an element. Atoms are composed of three kinds of smaller particles, called protons, neutrons and electrons. The number of protons, the number of neutrons and the number of electrons an atom has determines what the element it is.

Number of Neutrons - How to find the Number of Neutrons
We can identify the number of neutrons in an atom or element by subtracting the atomic mass number from the atomic number.

Number of Neutrons = Mass Number - Atomic Number

Number of Neutrons - Examples of Number of Neutrons
We Check out the following examples detailing the number of neutrons in specific elements.

Number of Neutrons = Mass Number - Atomic Number

• Example 1 - The element Gold (Symbol Au). The atomic mass number of gold is 197 and has the Atomic Number of 79. The Number of Neutrons in Gold is 197 - 79 =  118

• Example 2 - The element Silver (Symbol Ag). Neutrons in Silver: The atomic mass number of silver is 108 and has the Atomic Number of 47. The Neutrons in Neon is 108 - 47 = 61

• Example 3 - The element Neon (Symbol Ne). The atomic mass of neon is 20 and has the Atomic Number of 10.  Neutrons in Neon is 20 - 10 = 10
