Answer:
The correct option is 'Nitrogen has a larger radius and one less proton than oxygen.'
Step-by-step explanation:
Atomic number can be described as the number of protons in an atom. The atomic number of nitrogen is 7. This means that nitrogen has seven protons in its nucleus.
The atomic number of oxygen is 8 which means oxygen has 8 protons in its atom. Hence, oxygen has one more proton than a nitrogen atom.
The radius of an atom decreases when moving from left to right in the periodic table. Hence, the radius of nitrogen will be larges as compared with oxygen.
