What are pseudocore electrons? a. they are the electrons in the d and f subshells b. they are electrons in d and f subshells that are outside of the noble gas core c. the are the valence electrons of the noble gases d. none of the above

B. They are electrons in d and f subshells that are outside of the noble gas core

Explanation:

lectrons are sub-atomic particles that are found surrounding the nucleus of atoms in energy shells.Noble gases are elements that occupy group 8 of the periodic table. These elements have a stable configuration or an octet configuration since they do not require to lose or gain electrons for stability. Electrons may occupy the sub-shells s, p, d or f orbitals of an atom orbiting the nucleus.Pseudocore electrons are electrons in the d and f sub-shells outside the core of noble gases.
