Which group of elements will readily lose one electron to meet the octet rule? Alkaline Earth Metals c. Halogens Alkali Metals d
vova2212 [387]

Answer:

Alkali metals

Explanation:

The alkali metals are a group of metallic elements which are present in the first group of the periodic table. In other words, they are present in group 1 of the periodic table. These elements have one electron in their valence shell, the reason why they are placed in group 1.

They ionize by losing one electron to achieve the configuration of the nearest Noble gas or inert gas. Because they need to offset only one electron in their outermost shell, they are very chemically reactive and hence rarely occur in the free state.

Examples of elements in this group include lithium, potassium and sodium. They each have one electron only in their outermost shells.
