Question

How many orbital and how many electrons are there in each of the first two principal quantum number?

Answer 1

Answer:

Explanation:

The spin of one electron must be +1/2 while the spin of the other electron must be -1/2. There are three subshells in principal quantum level n=3. Since l=3 refers to the f subshell, the type of orbital represented is 4f (combination of the principal quantum number n and the name of the subshell).

Answer 2

Explanation:

Each orbital holds two electrons, because they also have one extraquantum number: ms, the spin quantum number. This can only take two values for electrons: −1/2 or +1/2. So for every orbital,there are a maximum of two electrons.
