Test Description: Periodic Trends
Instructions: Answer all questions to get your test result.
1) How does the atomic radius of Ca compare to K, and why?
A
Larger, because calcium has 1 additional proton in the nucleus.
B
Larger, because it has more electron repulsions.
C
Smaller, because calcium has 1 additional proton in the nucleus.
D
Smaller, because its electrons experience less shielding.
2) How does the atomic radius of Ba compare to Sr, and why?
A
Smaller, because it has a greater electronegativity.
B
Larger, because it has one additional occupied shell of electrons.
C
Smaller, because it has more protons in the nucleus.
D
Larger, because its electrons experience more shielding.
3) How does the ionic radius of F- compare to that of O-2?
A
Smaller, because it has one additional proton.
B
Larger, because it is more electronegative.
C
Smaller, because it has only gained one electron.
D
Smaller, because oxygen has more electron repulsions.
4) How does the first ionization energy of Ca compare to Be?
A
Smaller, because the valence electrons experience less shielding.
B
Smaller, because the valence electrons experience more shielding.
C
Larger, because it has more occupied shells of electrons.
D
Smaller, because it has more protons.
