Show hintHide hint
Think about how difficult it is to remove something from an atom.
Question 2.
Does ionization energy increase or decrease across a period?
Show hintHide hint
Recall the trend secret of nuclear charge.
3Question 3.
What does ionization energy refer to?
- Energy to form a bond
- Energy to remove an electron
- Energy to gain an electron
Show hintHide hint
Focus on what happens to the electrons in this process.
4Question 4.

- True
- False
Show hintHide hint
Remember how protons are changing as you move through the table.
Question 5.
Calculate and compare the ionization energies of potassium (K) and arsenic (As). Explain your reasoning based on periodic trends.
Show hintHide hint
Refer back to the shielding and distance concepts we've discussed.
Question 6.
Design an experiment to measure the ionization energy of a gas-phase element using a photoelectron spectrometer. Outline the key steps of your methodology.
Show hintHide hint
