Which atom generally obtains a stable configuration by sharing electrons? phosphorus (P)
magnesium (Mg)
lithium (LI
chlorine (CI)

are those the choices?

Explanation:

Phosphorus (P)

Explanation: Phosphorous has 5 valence electrons so it will share some to become stable.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
