alkaline earth metals (group 2 elements) have two valence electrons
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
The alkali earth elements have TWO valence electrons.
Lithium and Sodium both have 2 valence electrons.
Yes, elements with very few valence electrons are typically non-metals. Non-metals tend to have higher electronegativities, making them more likely to gain electrons to achieve a stable electron configuration. Elements with few valence electrons are more likely to gain electrons rather than lose them, leading to non-metallic properties.
