Question

true or false: the outer orbitals of a halogen are further from the nucleus and are thereby more polarizable.

Answer 1

False, A halogen's outer orbitals are more polarizable since they are located further from the nucleus.

What commonalities in the halogens' electron configuration are there?

You'll see that the outer shells of the atoms fluorine and chlorine both have seven electrons. All the halogens share that property of having seven electrons. All of them are only one electron short of having complete shells.

Why is it challenging to take an electron out of a halogen?

Ionization force It is the amount of energy needed to separate one mole of gaseous atoms from one mole of electrons. Non-metals called halogens have seven valence electrons. Due to their lack of a tendency to lose electrons, halogens have exceptionally high ionization energies.
