Question 1.
What does ionization energy measure?
Show hintHide hint
Think about removing something from an atom.
Question 2.
Is adding an electron to an atom generally an exothermic or endothermic process?
Show hintHide hint
Remember, exothermic processes release energy.
3Question 3.
What is ionization energy?
- Energy required to add an electron
- Energy needed to remove an electron
- Energy to maintain all electrons
Show hintHide hint
Think about what happens during a chemical change where electrons are lost.
4Question 4.
True or False: Electron affinity measures the energy change when an atom gains an electron.
- True
- False
Show hintHide hint
Consider whether gaining an electron involves energy being gained or released.
Question 5.
Compare and contrast the first ionization energies of sodium, magnesium, and aluminum. What trends do you observe?
Show hintHide hint
Look at the electron configurations and positions on the periodic table to clarify.
Question 6.
Given the following elements: fluorine, nitrogen, and oxygen, analyze their electron affinities. How does this affect their tendency to gain electrons?
Show hintHide hint
Consider how each element approaches a stable octet and the energy associated with electron addition.
