carbon and tin are both in the fourth column of the table which would you expect to have the greater electronegativity

The study of chemical bonds is called chemistry.

The correct answer is carbon.

The more negative charge present on an atom shows the electronegativity.

The attraction of the nucleus to the proton is also referred to as electronegativity.

The smaller the radius more the electronegativity.

Hence, the correct answer is Carbon as it has fewer atoms and a smaller radius.

Explanation:

electronegativity decreases when you go down a column

the answer is true.
