The group 2 of elements (alkaline earth metals) in the periodic table of Mendeleev contain beryllium, calcium, magnesium, strontium, barium and radium.
group 2 elements are alkaline elements.one of the element in d group is berrylium
+2 for group 2 elements
Group 1 elements are more reactive than that of group 2 elements.
2 elements
Because there in group 2
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.
helium has 2 valence has electrons. Group 2 elements also have 2 valence electrons.
Group 1 and group 2 elements are called s-block elements
Because there in group 2
group 2
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
The ist group elements Alkali metals are most active elements.
