Explanation:

Representative elements are the elements in groups 1, 2, and 13 - 18 of the periodic table. These groups are the tall columns (excluding the transition metal groups which are the short columns in the middle). Elements in the same row (period) have different properties. And while elements in a group (column) share some properties, the key characteristic for representative elements is their position in the tall columns.
