Answer 1

Compounds formed between elements on the far left and far right of the periodic table tend to be ionic. Those compounds formed between elements on the same side of the table (near each other) tend to be covalent. K and Br will be ionic. Ba and Cl will be ionic. O and F will be covalent as will SO2, SO3, NO2, IBr, etc.
