The elements sodium (na) has an atomic number of 11 with ine outer valence electron, this element would likely form

Cation. Sodium has 10 electrons with 1 outer valence electron, and outer valence electrons are positive. This means that it will have a charge of + 1, and a cation is a positively charged ion that is attracted to the cathode during electrolysis, which is the decomposition (chemically) of something that happens after an electric current passes through it.
