valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
Carbon, Nitrogen, and Oxygen all have the same number of energy levels because periods (rows) tell the amount of energy levels an element has.
Hey there!
The correct answer should be B. Potential Energy Only
Potential energy is the energy stored in an object because it isn’t moving/isn’t in motion
Hope this helps you!
God bless ❤️

Covalent bonds form when electrons are shared between two nonmetals. A covalent bond involves a pair of electrons being shared between atoms.
Atoms form covalent bonds in order to reach a more stable state.
A given nonmetal atom can form a single, double, or triple bond with another nonmetal. Which type of bond is formed between the atoms depends on their numbers of valence electrons.
