-
sodium and chlor, de
held together by​

Answer 1

Answer:

When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. The sodium (Na) atom transfers one electron to the chlorine (Cl) atom, so that they both have full outer shells. With filled outer shells they are no longer chemically active and can't form covalent bonds to become part of a molecule.

Explanation:

Answer 2

Answer:

The sodium ions and chloride ions are held together by the strong electrostatic attractions between the positive and negative charges. You need one sodium atom to provide the extra electron for one chlorine atom, so they combine together 1:1. The formula is therefore NaCl
