Classify the following compounds as having covalent or ionic bonds.

A. sulfur trioxide
B. potassium iodide
C. phosphorus trichloride
D. barium chloride
E. aluminum sulfide
F. strontium iodide
G. phosphorus trichloride

Ionic -

barium chloride , potassium iodide , aluminum sulfide , strontium iodide .

Covalent -

sulfur trioxide , phosphorus trichloride

Explanation:

Covalent bond -

Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.

It is the bond which is generally occurs within non metals as they share electrons to complete their octet.

The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .

Ionic bond -

It refers to the type of bond between two atoms , where the difference between the electronegativity is very high ( more than 1.7 ) .

Most of the salts are ionic in nature , and as soon as dissolved in water , dissociates into its respective ions .

Hence , from the question ,

The ionic bonds are -

barium chloride , potassium iodide , aluminum sulfide , strontium iodide .

And the covalent bonds are -

sulfur trioxide , phosphorus trichloride

the answer is learned

lol for the pointsss
