Given:

Atomic Number =10

Atomic Mass = 20

Determine the number of neutrons in the atom.

Solution:

To determine the number of neutrons, we refer to the general concept of atomic mass and atomic number

Atomic Mass = Atomic Number + Number of Neutrons

Number of Neutrons = Atomic Mass - Atomic Number

Substitute the given values of atomic number and atomic mass to the equation.

Number of Neutrons = 20 - 10

Number of Neutrons = 10

Final answer:

Number of Neutrons = 10
