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
