Question

Does oxygen have a larger atomic radius than nitrogen

Answer 1

Yes. Oxygen has a larger atomic radius than nitrogen.

REASON:
The electronic configuration of nitrogen is 2p​³ while that of oxygen is 2p4. According to the general concept, the atomic radii decreases as we move along the period from left to right. Thus, the atomic radii of oxygen should be smaller than that of nitrogen. But, this is not so. Oxygen has slightly larger atomic radii (74 pm) than nitrogen (70 pm). The reason lied behind the electronic configuration only.
In nitrogen, the 2p orbitals are half-filled (all three orbitals have one unpaired electron each), thus leading to stability. Oxygen, on the other hand has 2p4 configuration and thus has paired electrons in one of the three orbitals. Thus leads to greater replusion between the electrons which increases the atomic radii slightly.

Answer 2

Heya...

Here is your answer...

Oxygen have a smaller atomic radius than nitrogen.

Because the electrons in oxygen will be closer to the nucleus.

so when the electrons are closer the atomic radius will be smaller.

so oxygen have smaller atomic radius than the nitrogen.
