The space around the nucleus of an atom that electrons orbit

The electron cloud - or - electron orbitals

Explanation:

Protons and neutrons are held in the nucleus of the atom; electrons orbit around the nucleus in orbitals. Modern atomic theory tells us that these orbitals are not necessarily a circular or elliptical path but more like a cloud-like area where electrons are likely to be found at any given time.

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.
