Question

what is NaCl2

Answer 1

NaCl₂ is a compound of sodium in a higher oxidation state than normal. This compound does not exist. Here the sodium is present as the Na²⁺ ion, and the formation of this ion (with the electron configuration 1s²2s²2p⁵) would require the loss of two electrons from a sodium atom. Because the second electron must be removed from the n=2 shell, formation of Na²⁺ requires a substantial amount of energy.
