Step-by-step explanation:
True, the elements in a group of the periodic table have similar characteristics. The periodic table is arranged so that elements with similar chemical behaviors are in the same group. Groups are numbered 1-18 from left to right, and elements in the same group have similar chemical properties. For example, the elements in Group 1 are known as the alkali metals, Group 2 are the alkaline earth metals, Group 17 are the halogens, and Group 18 are the noble gases.
