Asked by Linda

Edexcel a level chemistry question: if 2 elements are closer to each other in the period table, does this mean that their covalent character is increasing? Many multiple choice questions ask to choose the row with increasing covalent character.?

Covalent character means that the bond between two atoms tends to be a sharing of electrons rather than a transfer of electrons as seen in ionic bonds. The difference in electronegativity determines the covalent character of a bond. The smaller the difference the higher the covalent character. So yes, two elements that are closer together have higher covalent character.
