Verified step by step guidance1
Understand that valence electrons are the electrons in the outermost shell of an atom that participate in chemical bonding.
Recall that metals are typically found on the left side and in the center of the periodic table, including groups 1, 2, and the transition metals.
Recognize that metals usually have relatively few valence electrons, which makes them prone to losing electrons and forming positive ions (cations).
Note that metals commonly have 1 to 3 valence electrons in their outermost shell, which explains their typical chemical behavior.
Therefore, the general number of valence electrons for metals is 1 to 3, distinguishing them from nonmetals that have more valence electrons.
