Question

why atomic radius of oxygen is greater than nitrogen

Answer 1

Answer:

oxygen has same number of shells as nitrogen. Thus electrons in oxygen atom will be closer to nucleus than in the case of nitrogen. ... When electrons are closer it means atomic radius is smaller. When electrons are farther away from nucleus atomic radius is also larger.

Answer 2

here is your answer mate.

yes oxygen has greater atomic radius than nitrogen because the eight protons in oxygen atom's nucleus will exert more force than nitrogen's seven electrons. Also, oxygen has same number of shells as nitrogen. Thus electrons in oxygen atom will be closer to nucleus than in the case of nitrogen. ... When electrons are farther away from nucleus atomic radius is also larger.
