Question

Name any two elements of group one and writ their electronic configurations what similarity do you observe in their electonic configuration write the formula of ocide of any of thr a foresaid element

Answer 1

Two elements in group 1 are Na and K,which are sodium and potassium.

Na=2 ,8,1

K=2,8,8,1

We Observe that both have 1 valence electron in their outermost shell. Hence both have valency 1

Formula of oxide in group 1 is R(SUB)2O. Where R is denoted by the element. Similarly formula of oxides of Na and K must be Na(sub)2O and K(sub)2O.

I have used (sub) for subscript...
