How do you know when an atom has higher electronegativity? ex) ClO, BrO, IO

Periodic trends say that the closer to fluorine an atom is the more electro negative.

For electronegativity of atoms, there is a general trend in the periodic table that the upper right corner has higher electronegativity. So when comparing electronegativity of two atoms, simply check their relative positions to Florine which has the highest electronegativity. The closer the atom is, the higher electronegativity it has.

In your examples, since O and Cl are both very closed to F, you would have to look up specific values, and it would be Cl with a higher electronegativity.

Using the generic trends of the periodic table, the more electronegative atoms are found in the upper right hand corner of the table.

So I assume with these compounds you just compare the atoms individually to figure out which is more electronegative?

The greater the difference in the electro negativity between the two atoms is generally the way to determine which is more electronegative.
