When a nitrogen atom becomes an ion, the atom becomes a... A. Negative ion with a radius smaller than the radius of the atom B. Negative ion with a radius larger than the radius of the atom C. Positive ion with a radius smaller than the radius of the atom D. Positive ion with a radius larger than the radius of the atom

B. Negative ion with a radius larger than the radius of the atom

Explanation:

When a negative ion is formed, electrons are added to the atom. As electrons are added to the atom, the size of the electron cloud increases accordingly.

As a result of this, a negative ion is always larger than its corresponding atom. Hence, nitrogen ion must be larger than the nitrogen atom based on the facts stated above.
