Question

How is an anion formed?
​

Answer 1

Answer:

Anions are the negative ions formed from the gain of one or more electrons. When nonmetal atoms gain electrons, they often do so until their outermost principal energy level achieves an octet. ... Under typical conditions, three electrons is the maximum that will be gained in the formation of anions.

Explanation:

Metallic atoms hold some of their electrons relatively loosely. Consequently, they tend to lose electrons and form cations. Conversely, most nonmetallic atoms attract electrons more strongly than metallic atoms, and so gain electrons to form anions.
