Answer:There are 18 electrons and 17 protons, so the chlorine atom has become a charged chlorine ion with a charge of negative one (-1). ... When it does, the sodium atom becomes a sodium ion with a charge of positive one (+1). Chlorine, as mentioned above, desperately wants an electron so it can fill its outer electron level.
Its A. the energy is stored within the nuclear of the atom
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)
