Expert Answer:

i) The element (M) with atomic number 114 belongs to group 14 of the periodic table so it will exhibit a valency of 2 (due to inert pair effect) and 4. The stable binary compound between this element and fluorine would have the formula MF2.
ii) The element (X) with atomic number 120 belongs to group2. Its valency would be 2. Thus, the formula of the compound between this element and Oxygen would have the formula XO.
