Step 1 of 3

Solution 75P

Here, we have to identify the element with each configuration.

(a) [Ne]3s23p5

The atomic number of the element is 17

From electronic configuration, valence electron of the element = 7

Thus, it is an element of Group 17 (VIIA).

Therefore, the name of the element is Chlorine (Cl).

(b) [Ar]4s23d104p1

The atomic number of the element is 31

From electronic configuration, valence electron of the element = 3

Thus, it is an element of Group 13 (IIIA).

Therefore, the name of the element is Gallium (Ga).

(c) [Ar]4s23d6

The atomic number of the element is 26

From electronic configuration, valence electron of the element = 8

Thus, it is an element of Group 8 (8B).

Therefore, the name of the element is Iron (Fe).

(d) [Kr]5s1

The atomic number of the element is 37

From electronic configuration, valence electron of the element = 1

Thus, it is an element of Group I (IA).

Therefore, the name of the element is Rubidium  (Rb).
