Hydrogen, above group 1; Carbon in Group 14; oxygen, sulphur and selenium in Group 16; all the halogens in group 17; all the noble gases in Group 18.
Alkali metals are group-1 elements. They are located at extreme left in periodic table.
Halogens: F (Fluorine), Cl (Chlorine), Br (Bromine), I (Iodine), At (Astatine), Uus (Ununseptium) located on the right of the periodic table of elements.
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
Metals are everything from the left side to a diagonal line between aluminum and bismuth.
The alkali earth metals are in the 2nd group, or column of the periodic table. They are bordered by the alkali metals on the left and the transition metals on the right.
Transition metals are located in group 3-12 of the periodic table. The middle of the periodic table.
Alkali metals are group-1 elements. They are located at extreme left in periodic table.
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
Non metals are located on right side in Periodic Table. They are present in group-15,16,17.
