Q: What do covalent bonds give atoms a more stable arrangement of?


Read this paragraph and choose the correct option from the provided answers:

Covalent bonds form because they give atoms a more stable arrangement of electrons. Look at the oxygen atoms in the Figure above . Alone, each oxygen atom has six valence electrons. By sharing two pairs of valence electrons, each oxygen atom has a total of eight valence electrons. This fills its outer energy level, giving it the most stable arrangement of electrons. The shared electrons are attracted to both oxygen nuclei, and this force of attraction holds the two atoms together in the oxygen molecule.

 Choices:

- protons

- neutrons

- cell walls

- electrons


A:
electrons
