By same kind, you mean the same element I guess?

What element you have is determined by the number of protons.

The number of neutrons can vary (isotopes). The number of electrons can vary (ions). The electrons or nucleons could have extra energy from being excited.

But the number of protons determines what we call it.

They have the same number of protons.
