Question

What factors that affect ionization energy?

a.
Group number, atomic mass, electron configuration, density
c.
Weight, state at room temperature, density and ionic radius
b.
Only the charge matters
d.
Charge, atomic radius, orbital penetration, and electron pairing

Answer 1

What are the factors that affect ionization energy



there are five factors which can affect the Ionization energy like size of an atom,The effective nuclear charge,Shielding effect,Penetration effect and electronic configuration of an atom.All these factors related to the number of electrones in the valence shell and between the valence shell and nucleus

Answer 2

Size of an atom,The effective nuclear charge,Shielding effect,Penetration effect and electronic configuration of an atom.

I'm not sure which of yours is correct but i hope this helps.
