Question

Electrons in the 3s and 3p orbitals of hydrogen are at ___________ energy level(s), and electrons in the 2s and 3s orbitals of hydrogen are at ____________ energy level(s).

a. the same; different

b. different; different

c. different; the same

d. It is impossible to determine the relative magnitudes of the energies of the different orbitals.

Which of the following is the best explanation of why it is harder to remove an electron from an atom of neon than an atom of fluorine?

a. Neon has more electrons than fluorine, so it is less likely to give one up.

b. It is harder to remove an electron from neon than fluorine because of increased nuclear charge (Z = 10).

c. Electrons are easier to remove from elements that form diatomic gases, in general.

d. Removing an electron from neon would require formation of an unpaired 2p electron.
