A cation. It is by definition an atom that has lost one or more electrons. Since an electron has a negative 1 charge by designation, having a less negative charge by x gives a higher positive charge by x. That is, you form the ion "M"^(x+) for x number of electrons lost.

What is the common charge of the barium cation?
