2.
FLASHCARD QUESTION
Front
How does ionization energy change across a period in the periodic table?
Back
Ionization energy generally increases as you move from left to right across a period due to increasing nuclear charge.
3.
FLASHCARD QUESTION
Front
How does ionization energy change down a group in the periodic table?
Back
Ionization energy generally decreases as you move down a group because the valence electrons are further from the nucleus.
4.
FLASHCARD QUESTION
Front
What is the trend of ionization energy for alkaline earth metals?
Back
For alkaline earth metals, ionization energy decreases as the atomic number increases.
5.
FLASHCARD QUESTION
Front
Which element has a higher ionization energy: sulfur or chlorine?
Back
Chlorine has a higher ionization energy than sulfur.
6.
FLASHCARD QUESTION
Front
What is the relationship between atomic radius and ionization energy?
Back
As atomic radius increases, ionization energy generally decreases because the outer electrons are further from the nucleus.
7.
FLASHCARD QUESTION
