group 2 elements are alkaline elements.one of the element in d group is berrylium
All the chemical elements from group I and II are very reactive; it is impossible to found these elements in nature in elemental state.
nitrogen and phosphorus
The alkaline earth metals are the elements found in group 2 of the periodic table. They include beryllium, magnesium, calcium, strontium, barium, and radium.
group 18 has completely filled electronic configuration and hence are stable. group 1 and group 2 have 1 and 2 electrons respectively in their valence shells and needs to lose these to attain completely filled electronic configuration. hence they are reactive.
+2 for group 2 elements
Group 1 elements are more reactive than that of group 2 elements.
The six elements commonly recognized as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium and are found in group 14-16
2 elements
Because there in group 2
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.
these elements are found in all institutions of the world societies: 1: it is a group of people who are inerrelated through social interaction. 2:this is a group of people is united under common interest.
helium has 2 valence has electrons. Group 2 elements also have 2 valence electrons.
