question
Among the elements of the main group, the first ionization energy increases
answer
not b from right to left across a period.
question
Which is most likely true about electronegativity?
answer
not b It tends to be the same down a group.
question
How does a lithium cation compare to a lithium atom?
answer
C - The cation is smaller.
question
Which correctly summarizes the trend in electron affinity?

question
Which is true of transition metals when moving from left to right on the periodic table?
answer
not c/b Atomic radii increase slightly and then start to decrease.
question
Among the elements of the main group, the general trend in the first ionization energy moving across a period is not followed between group 2 and group 13. Which best explains these exceptions?
answer
A - The ionization energy decreases because the full s orbital shields the electron entering the p orbital.
