Answer:
The 2 elements who can form ionic bond is Li and F. It will form an ionic compound known as Lithium Fluoride.
Explanation:
Ionic bond is formed between metal and non-metal element wherein, metal loses electron to become positively charged cation and non-metal gain electron to become negatively charged anion base on octet rule. There will be electrostatic attraction between cation and anion element creating ionic bond.
Base on the given Data:
Li (lithium) - Cation
F (Fluorine) - Anion
Si (Silicon) - is unstable, it can be cation or anion but can only bond with other element covalently.
Ne (Neon) - is a noble gas it will not likely form a bond on other element since it has a full share of valence electron.
