Answer:
A Cation is an element that tends to lose electrons during a chemical reaction or when it bonds. It is found on the far left side of the periodic table (e.g under hydrogen or beryllium aka periods 1 and 2) but there are some exceptions like Aluminum which is on the right side. Most metals also tend to lose electrons during ionic bonding so I would include metals (which are right in the middle) of the periodic table if you have learned about their bonding tendencies.
Explanation:
It is easier for an atom on the left side of the periodic table to lose 1, 2, or 3 electrons during ionic bonding than to gain 8 to form a stable octet because these atoms have a fewer number of electrons than elements on the right side of the table in the same row (period)
