Question

Pls solve this with full steps.(Chemistry)

Answer 1

Answer:

No. of protons =18= atomic number of an atom

No. of electrons =18= atomic number of an atom

No. of neutrons =40−18=22

Answer 2

Answer:

neutron are 22

electrons are 18

protons are 18

Explanation:

atomic no is equal to the no of electrons and protons so 18 electrons and 18 protons

no of neutrons  are equal to the

                                 mass number - atomic number

                  so            40 - 18

no of neutrons          22
