  1. Your formulas are right.
    In general, ionic bonds are formed when elements from the sides of the periodic table (left side and right side) combine. Examples are LiCl, BaCl2, AlCl3 etc.
    In general, covalent bonds are formed when elements from the center combine with left or right side elements (examples are CH4, CCl4, SiCl4) OR when elements from the same side combine with each other (examples are Cl2, Br2, I2, F2, O2, N2, ClF, ).
