Plz sir help me on this chemistry question. Configuration of element X and Y are as follow... X = 2,8,8 and Y = 2,7 (1). Write the formula of the compound formed when they combine (2) Name the type of bonding involved.

Ar and F2 do not form a compound, at least not easily. Check you post to see if it is accurate.

2. If a compound did form it would be due to sharing electrons.
