What are groups of 1, 2, and 3 examples of on the periodic table? a. metals b. nonmetals c. metalloids d. noble gases

Hello Cs1011200,

How are you doing? Groups are placed vertically in each line on the periodic table. So Group 1, 2, and 3 are the first three to the left. If you notice, Group 1 is Alkali Metals, group 2 is Alkali Earth Metals, and group 3 is Transition Metals. If you notice, all three are metals! Therefore, A. should be your answer. Hope I helped.

Thank you,
Darian D. 

Iwould have to say sorry i can't elaborate more. hope this though!
