alkaline earths
Group two elements
The alkaline earths are a group of six metallic elements in the second column of the periodic table: beryllium, magnesium, calcium, strontium, barium, and radium.
They share similar chemical properties—forming alkaline (basic) solutions when their oxides react with water.
Calcium and magnesium are the most familiar, essential to bones and abundant in limestone.
