In long form of periodic table, an elem ...

In long form of periodic table, an elem ent has electronic configuration`Is^(2) 2s^(22)p^(6)3s^(2)3p^(3)` Thus what will be the atomic no. of elem ent ? Which is just below this elem ent in its group ?

A

23

B

16

C

47

D

33

Text Solution

Verified by Experts

The correct Answer is:
D

The given configuration indicates Z = 15, and outerm ost configuration `3s^(2) 3p^(3)` ..... indicates group `15^(th) , row 3^(rd) therefore` Next row `4^(th)` and group `15^(th)` element will behaving Z = (15 + 18) = 33
