Identify and name the metals out of the following elements whose electronic configurations are given below.

It is given that: n(S) = 21, n(T) = 32, n(S ∩ T) = 11  We know that: n (S ∪ T) = n (S) + n (T) – n (S...

It is given that: n(X) = 40, n(X ∪ Y) = 60,  n(X ∩ Y) = 10  We know that:  n(X ∪ Y) = n(X) + n(Y) – n(X ∩ Y)  ∴ 60 = 40...

(a) Na (Z = 11) has outermost electronic Configuration = 3s1 (b) N (Z = 7) has outermost electronic Configuration = 2p3 (c) Fe (Z = 26) has outermost electronic Configuration =...

(c) either metals or non-metals 

The elements in the first-half of the transition series exhibit many oxidation states with Mn exhibiting maximum number of oxidation states (+2 to +7). The stability of +2 oxidation state increases...

Two elements of group 1 are Sodium (Na) and potassium (K). Their electronic configurations: Na = 2,8,1; K : 2,8,8,1 Similarity: Both have one valence electron. Formula of their oxides: Na2O; K2O.

It is given that: n(S) = 21, n(T) = 32, n(S ∩ T) = 11 We know that: n (S ∪ T) = n (S) + n (T) – n (S...

It is given that:  n(X) = 40, n(X ∪ Y) = 60, n(X ∩ Y) = 10  We know that: n(X ∪ Y) = n(X) + n(Y) – n(X ∩ Y)  ∴ 60 = 40...
