Front

What is a valence electron?

Back

A valence electron is an electron that is associated with an atom and can participate in the formation of a chemical bond.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the molecule's structure and properties.

Front

Define polar molecule.

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a partial positive charge on one end and a partial negative charge on the other.

Front

Define nonpolar molecule.

Back

A nonpolar molecule is a molecule that does not have a net dipole moment, meaning the charge distribution is even, and there are no distinct positive or negative ends.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
