Alkali Earth metals are the most reactive metals on the periodic table.
There are many groups in the periodic table that only contain metals. There are the Alkali metals, the Alkaline earth metals, Lanthanoids, Actinoids, Transition metals, and the Post-transition metals.
its the boron group which contains one metalloid and 5 metals
Group A is an obsolete symbol for groups; the old groups IA and IIA contain alkali metals and alkali earth metals.
The groups 1-12 from the periodic table of Mendeleev contain only metals.
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
Alkaline earth are group2 metals in the periodic table of elements.
At Room Tempeture, Metals contain the most Elemants.
Metals are placed in group 1 (alkali metals) and group 2( alkaline earth metals) of the Periodic Table.
Group 1 elements are called alkali metals and all have a single electron in their outer shell/valence shell. These alkali metals are: Lithium (Li) Sodium (Na) Potassium (K) Rb (Rubidium) Caesium (Cs) Francium (Fr)
alkaline earth metals
Group 17 and 18 does not contain any metal.Group 17 belongs to halogens and group 18 belongs to noble gases.All the elements are non metals.
The alkali metals are group 1, also known as group 1A.
