How many orbitals are there in the third shell (n=3)?

9

Explanation:

Hello,

In this case, since the third shell of electrons has  the following 3 subshells:

- The subsehll has one orbital for one pair of electrons: .

- The subsehll has three orbitals for three pairs of electrons: .

- The subsehll has five orbital for five pairs of electrons .

Therefore, the total number of orbitals when n=3 is:

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
