Question

can you walk me through this. I dont understand the x, y, z. I know how to do long form electron configuration but dont understand this.

What elements are described by the following electron configurations.

1. 1s2 2s2 2p3 3s2 3px2 3py1 3pz1

2. (Kr) 4910 5px1 5px1 5s2

Answer 1

To place electron in atom, we have four sub-shell present in the shell and they are s, p, d and f.

All sub shell has particular number of orbitals. Orbitals are the three dimensional path where electron and its cloud is present by which electrons are moving around the nucleus.

S sub-shell has 1 orbital

P sub-shell has 3 orbital that means

Here in question x , y and z are denote the orbitals of P sub-shell

1. The following electronic configuration is for the Sulfur(S)

and its configuration is
