Bond polarity question please

Consider the following element combinations
i get the next elements:

S-I
H-Br
H-P
S-O
Be-F
Be-Cl
Sc-O

Classify the bonds formed between each pair as ionic, polar covalent, or nonpolar covalent based on each element's position in the periodic table.

First, you need to find out the electronegativity of each element on this periodic table:

scroll down, you will see a table with Fluorine, for example, having a 4.0 - they are blue numbers.
Find each element in your compound, for example, S is 2.5, and I is 2.7.
Subtract them - 2.5 - 2.7 = .2

Now go to this web site, and look up .2 on the chart...
scroll down.... 3 image down

now, .2 on the chart is polar covalent bond.
Done, now move to the next one!
Good Luck!
