S BLOCK ELEMENTS
those compounds in which highest energy electrons
are present in s sub energy level is called s block elements.
Group 1st A and 2nd A elements are called s block elements
Na =11 = 1S2,2s2,2p6,3s1
Mg = 12 = 1s2,2s2,2p6,3s2

hey mate!
here is your answer:
the first two groups of a mordern periodic table are known as S block elements.
the first group elements are alkaline and soft elements and usually lighter in weight than that of other groups and they are silvery white in colour, the second period elements are known as alkaline earth metals and are comparatively heavier in weight from first group and they are white in colour.
firat group element=hydrogen, lithium,sodium,potassium,rubidium,caesium and francium
second group elements=beryllium, magnesium, calcium, strontium, bariumand radium
hope it helepd!
