How many valence electrons are there in Sodium?
It is interesting to know the fact that Sodium has one valence electron. Keep in mind the fact that valence electrons are the outermost electrons. They are the ones involved in bonding. Sodium has 11 electrons. Moreover, its atomic number is 11, so it has 11 protons. Needless to say, a valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond.
