Decaying uranium atoms in earth’s crust result in
a. u-235
b. explosions
c. high-level waste
d. radon gas

Decaying uranium atom in rocks and soil does not produce an explosion, high-level waste or u235 but it produces radon gas.  A radioactive decay which also in time turns to lead. This radioactive gas is one of the causes of lung cancer even to non-smokers.

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
