Question 1.
Define ionization energy.
Show hintHide hint
Think about the process of removing an electron.
Question 2.
What is the trend of ionization energy across a period?
Show hintHide hint
Consider the nuclear charge as you move from left to right.
3Question 3.
What is ionization energy?
Show hintHide hint
Remember, it's related to atom stability.
4Question 4.
True or False: Ionization energy increases as you go down a group.
Show hintHide hint
Think about the effect of additional electron shells.
Question 5.
Given the ionization energy values: Li (520 kJ/mol), Be (900 kJ/mol), B (800 kJ/mol), C (1100 kJ/mol), identify a potential reason why B has a lower ionization energy than expected.
Show hintHide hint
Consider the stability of half-filled versus filled states in electron configurations.
Question 6.
Explain why removing an electron from an atom with a noble gas configuration requires significantly more energy.
Show hintHide hint
Think about how atoms prefer stability versus instability.
