Ahypothetical metal crystallizes with the face-centered cubic unit cell. the radius of the metal atom is 234 picometers and its molar mass is 195.08 g/mol. calculate the density of the metal in g/cm3.

Explanation:

As can be seen in the Figure in a face-centered cubic unit cell you have:

Six halves of atomsEight 1/8 of atom (1 in each corner)

In total:

Now, each side of the cell is 234 picometers (2.34e-8 cm) long

Atoms per cm3:

Expressing in mass:

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.
