You can tell an element's group from its position in the periodic table. The groups are the PT's columns; they are numbered from 1 to 8, (or 1-18 (although sometimes the last group is also called group 0)).
To determine an element's group, count along the columns from the left. So potassium (K) is in the first row from the left, so it is group 1. Carbon (C) is in the forth row from the left, since we skip over the transition metals, so is in group 4. Neon (Ne) is in group 8.
