How many valence electrons do the elements of alkali metals have. How old was queen elizabeth 2 when she became queen? Alkali then alkaline. The general form for the electron configuration of each alkali metal is ns 1, where the n refers to the highest occupied principal energy level. As a result, the binding energy of alkali metal ions in the close-packed metal lattices are weak. In group 14, it has 4 valence electrons. Well, it depends. 1. In group 1, the alkali metals have 1 valence electron. this is why they are so highly reactive and cannot be found pure in nature. However, there are a number of exceptions to the rule; for example atomic number 46 has no electrons in the fifth shell, unlike other atoms with lower atomic number. Why are alkali metals soft and have low melting points? Sciences, Culinary Arts and Personal For a group number less than 5, the group number is simply the number of valence electrons. remember that alkali and alkaline go with columns 1 & 2 of the Lithium is the lightest metallic element.
