What is the number of valence electrons for the element beryllium? Please help.
Isn't it in group 2? So it must be two.
To find the number of valence electrons for an element, you need to look at the element's position on the periodic table. Beryllium is located in Group 2 of the periodic table.
Group 2 elements are known as the alkaline earth metals, and they have two valence electrons. This means that beryllium, being in Group 2, also has two valence electrons.
So, the number of valence electrons for the element beryllium is 2.
