In the above diagram, the block is at static equilibrium on the ground. what is the value of the force exerted by the ground on the block if the force due to gravity is 12 newtons?
a.
20 newtons
b.
12 newtons
c.
-12 newtons
d.
-20 newtons
e.
0 newtons

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.
