Question

Which element is in the p-block and has atoms containing two unpaired electrons in the ground state

Answer 1

Answer:

Oxygen.

There are two unpaired electrons in an atom of oxygen in its ground state.

Answer 2

Explanation:

There are two unpaired electrons in an atom of oxygen in its spot state. It is explained below

• According to the Aufbau Principle, atoms fill the subshells in the form of their growing force level. Then for oxygen electron having atomic no 8, the electronic arrangement will be
• 1s2 2s2 2p4

• Now P subshell has three immoral orbitals. According to Hund's rule of highest multiple for two or larger orbitals of same force atoms will occupy them once before packing them in pairs. Therefore the oxygen, the p orbitals will be arranged like

• 2px1 2py1 2pz1

• 2px2

Therefore Oxygen particle in its ground state has two unpaired particles.
