Question

which electrons typically have lower ionization energies in an atom? * transition metal electrons inner shell electrons valence electrons nucleus - adjacent electrons

Explanation:

Ionization energy is the energy required to remove an electron from an atom. Inner - shell electrons are closer to the nucleus and more strongly attracted to it. Valence electrons are in the outermost shell and are more easily removed as they are further from the nucleus and often shielded by inner - shell electrons. Nucleus - adjacent electrons is not a standard term in this context. Transition metal electrons is a broad and not the most relevant here compared to valence electrons. So valence electrons typically have lower ionization energies.

Answer:

Valence electrons
