Question

use the electron configuration of oxygen to explain why it tends to form a 2 - ion.
match the items in the left column to the appropriate blanks in the sentences on the right.
the electron configuration of oxygen is. by two electrons to form the 2 - ion, the electron configuration of the oxygen ion becomes the same as a noble gas. the noble gases are

Explanation:

Oxygen has 8 electrons. Its electron configuration is \([He]2s^{2}2p^{4}\). Noble gases have stable electron configurations. By gaining two electrons, oxygen achieves the electron configuration of neon (\([Ne]\)), which is stable. Noble gases are stable.

Answer:

The electron configuration of oxygen is \([He]2s^{2}2p^{4}\). By gaining two electrons to form the \(2 -\) ion, the electron configuration of the oxygen ion becomes the same as a noble gas neon. The noble gases are stable.
