What is the oxidation number for sodium?
A
2-
B
1+
C
2+
D
1-

B.) 1+

Explanation:

To obtain a full outer electron shell, sodium must lose one electron, leaving it with a plus one charge.

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.
