Hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen.
metals occur within groups 1 , 2, 3,4, and the transition metals
There are two groups that compose entirely of metals. The 1st group is alkaline earth the second is Aluminum.
The 38 elements in groups 3 through 12 of the periodic table are the transition metals.
families determine the energy level of an element and groups determine their properties.
The columns are groups or families. The rows are periods. The groups are numbered 1 to 18, with certain other distinctions. Group 18 is known as the noble gases. There are also larger groupings in to categories such as metals, non-metals, transistion metals, metaloids, etc.
The transition metals are located in groups 3 - 12 on the Periodic Table.
Groups 14 and 15 on the Periodic Table feature elements which are metals, non-metals, and metalloids.
Non-metals
Metals, Metalloids, and non-metals
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
