Question

Nitrogen is to the immediate left of oxygen in the same row in the periodic table. Which of the following statements compares the radius and number of protons of nitrogen and oxygen atoms?
Nitrogen tus a smallerades and one less proton than oxygen
Nitrogen has a larger radius and one less proton than oxygen
Nitrogen has a s
e
radius and one more proton than oxygen
Nitrogen has a gradus and one more proton than oxygen

Answer 1

Answer:

The correct option is  'Nitrogen has a larger radius and one less proton than oxygen.'

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.
