Question

28. What are the necessary conditions to an atom to form an anion​

Answer 1

Answer:

Annyeonghaseyo!!

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. This process is illustrated below for the elements fluorine, oxygen, and nitrogen.

Answer 2

$\huge\underline\mathtt\red{ANSWER:}$

An anion has more electrons than protons, consequently giving it a net negative charge. For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them.
