Here's a more detailed breakdown:

* Groups 1 & 2 (alkali and alkaline earth metals): These are all metals and occupy the far left side of the periodic table.

* Groups 3-12 (transition metals): These are also all metals and occupy the central block of the periodic table.

* Lanthanides and Actinides: These are also metals and are located at the bottom of the periodic table, separated from the main body.

Note: There are some exceptions, such as hydrogen, which is a non-metal despite being located in Group 1.
