Group 2 of the Periodic Table contains Alkaline Earth metals such as Beryllium, Magnesium, Calcium, Strontium, Barium and Radium.
The elements in group 2 are:
Beryllium (Be)
Magnesium (Mg)
Calcium (Ca)
Strontium (Sr)
Barium (Ba)
Radium (Ra)
They are alkaline earth metals. They have 2 valence electrons. Be,Mg,Ca.Sr,Ba are in this group.
Group 2 elements are called alkaline earth metals. They form cations to react.
Alkaline Earth Metals.
Group 1 elements are more reactive than that of group 2 elements.
helium has 2 valence has electrons. Group 2 elements also have 2 valence electrons.
Elements from the group 2 of the periodic table form cations.
2
The elements of the second group are called the Alkaline Earth metals.
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
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.
group 2
The ist group elements Alkali metals are most active elements.
