Fernanda · Answer 1

Neutron number = 12

Electron number = 10

Explanation:

Data obtained from the question include:

Atomic number = 10

Mass number = 22

Neutron number = ?

Electron number = ?

Proton number = atomic number = 10

Mass number = Neutron + proton

Neutron = Mass number - proton

Neutron number = 22 - 10

Neutron number = 12

Since the atom is neutral, the protons and the electrons are equal i. e

Electron number = proton number

Electron number = 10
