What is the definition of ionization energy?
The minimum energy required to remove an electron from a gaseous atom
What is the definition of electron affinity?
The negative of the energy change when an electron is accepted by an atom
Which orbital are electrons always removed from first when a cation is formed from a transition metal atom?
ns orbital
