It would form an anion. This element would likely form an anion because it has one negative charge which is represented by the one valence electron.

Hope this helps!

Explanation:

When a neutral atom loses an electron then it develops a positive charge and results into the formation of a cation.

For example, Na is an alkali metal with atomic number 11 and its electronic distribution is 2, 8, 1.

So, in order to become stable it loses its 1 valence electron and thus is forms [tex]Na^{+}[/tex] ion.

Thus, we can conclude that the element sodium (Na) has an atomic number of 11 with one outer valence electron, this element would likely form a cation.
