Which is true concerning the difference between second-row andthird-row main group nonmetals?
Select one:
a. Third-row nonmetals react readily with acids, whilesecond-row nonmetals are mostly unreactive towards acids.
b. Third-row hydrides tend to be more acidic than second-rowhydrides. (Incorrect)
c. Third-row oxides tend to be less basic than second-rowoxides.
d. In their elemental forms, third-row nonmetals are comprisedof molecules, while second-row nonmetals are comprised ofindividual atoms.
e. Atoms of third-row nonmetals may have high oxidation numbers,while atoms of second-row nonmetals may only have negativeoxidation numbers.
