What happens when sunlight strikes a photovoltaic cell?
a: electrons are released, causing a flow of electrical current
b: atoms are split, resulting in a release of energy
c: small tubes of water are heated, producing flow of energy

Which statement explains why the bonds between non metals tend to be covalent? the bonds are found to be nondirectional they have large differences in electronegativity they have small differences in electronegativity they have ions that produce an electrostatic pull
