Halogens have seven electrons in their valence shell, so they only need one more electron to obtain a completely filled valence shell. In addition, the unpaired electron in the seven electron shell is a radical which is highly reactive.

The periodic table of elements is organized in order of atomic number, whic describes how many protons are found in the atom's nucleus. The position of the element in the periodic table can also yield insight into how that atom will respond to other atoms and how it will participate in a chemical reaction.
Sodium is found in the alkali metal group on the periodic table. What type of ion would you expect sodium to form in order to achieve a stable octet?

Sodium is found in the alkali metal group on the periodic table. What type of ion would you expect sodium to form in order to achieve a stable octet?
Tap to reveal answer
Sodium is an alkali metal. All alkali metals are found in group 1 on the periodic table, and lose 1 electron in order to achieve a stable octet. Any ion that loses an electron, and thus becomes positively charged, is referred to as a cation. Anions are negatively charged ions, so sodium is not going to become an anion.
