Democritus, a Greek philosopher.
The number of protons can be calculated by subtracting 207 with 125
Therefore, proton no. : 207 - 125
= 32
Proton number and electron number is always equivalent, so there are 32 electrons in the electron shells
Protons and neutrons are always located in the nucleus of an atom, and electrons are located in the electron shells which always move rapidly around the atom
The element which is referred is Lead(Pb)
