Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity determines how strongly an atom attracts shared electrons in a bond.

Front

What is the difference between a polar and nonpolar covalent bond?

Back

A polar covalent bond has unequal sharing of electrons, while a nonpolar covalent bond has equal sharing.

Front

How do you determine the number of bonds an element can form?

Back

The number of bonds an element can form is determined by its valence electrons.

Front

What is the general rule for naming covalent compounds?

Back

Use prefixes to indicate the number of atoms and the suffix '-ide' for the second element.
