Question

Which of the following statements are false?

It takes less energy to add an electron to nitrogen than to carbon because nitrogen will be closer to achieving a noble gas configuration.

It takes more energy to add an electron to fluorine than to oxygen because the radius of fluorine is smaller and more repulsion would occur in the p-orbitals.

It takes more energy to add an electron to nitrogen than to carbon because of the extra repulsions that would occur in the 2p orbitals.

Less energy is released in adding an electron to iodine than to chlorine because the radius of iodine is larger and the electron is added at a distance further from the nucleus.

II, III

I, II, IV

III only

I, II

All of the these are false statements.

Explanation / Answer

III only. It takes more energy to add an electron to nitrogen than to carbon because of the extra repulsions that would occur in the 2p orbitals. due to the presence of unshiled protons. it is easier to add with less energy.
