| How are the electrons transferred? (from metal to non-metal or non-metal to metal) | The electrons are transferred from metal to non-metal. |
| Sodium 1s2 2s2 2p6 3s1 Chlorine 1s2 2s2 2p6 3s2 3p5 Which atom will gain an electron and which atom will lose an electron? | Chlorine will gain an electron to fill 3p and sodium will l lose 3s1. |
| If Chlorine gains a negatively charged electron will Chlorine become Cl+ or Cl- | Chlorine become Cl- because it has gained an negatively charged electron. |
| If Sodium has lost an negatively charged electron will it become Na+ or Na-? | It will become Na+ because it has lost an negatively charge electron. |
