And they're found from left all the way up to this section here. Now the orange guys are known as metalloids, while the red guys are known as nonmetals. Now group 18 is called the Noble gas group, while group 17, the group right next to group 18, are known as halogens. Now these guys here from this group to group number three are called transition metals.
