Back (Answer)

positive

#19
Front (Question)

chemical reaction representing the ionization energy for a chlorine atom

Back (Answer)

Cl → Cl⁺¹ + e⁻

#20
Front (Question)

chemical reaction representing the electron affinity for a chlorine atom

Back (Answer)

Cl + e⁻ → Cl⁻¹

#21
Front (Question)

Ionization energy (IE)

Back (Answer)

the energy needed to remove an electron from an atom

#22
Front (Question)

Electron affinity (EA)

Back (Answer)

energy absorbed or released when an atom gains an electron

#23
Front (Question)

Ionization energy is always ________

Back (Answer)

positive

#24
Front (Question)

• electron affinity energy is positive when __________ • energy is negative when ___________

Back (Answer)

• The energy is negative when the atom really wants the electron to become stable • the energy is positive when the atom does not want the electron because it is already somewhat stable • if the electron has a strong pull for or away, the energy will be high. if the pull is not as strong, the energy will be low
