    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
