Answer 1

It has the same number of protons as electrons, but it has a greater number of

neutrons.

Step-by-step explanation:

Atomic mass= number of proton + no. of neutron

If the number of proton is 36 and mass is 84, let's find it;

Atomic mass= number of proton + no. of neutron

84=36+no. of neutron

84-36= no. of neutron

48= no. of neutron

we can see, that no. of neutron is greater than no. of proton
