Question: What is the total number of orbitals in the n=2 shell?

Options:

Correct Answer: 4

Solution:

The n=2 shell has 4 orbitals: 1s and 3p orbitals.

What is the total number of orbitals in the n=2 shell?

What is the total number of orbitals in the n=2 shell?

Step 1: Understand that 'n' represents the principal quantum number, which indicates the energy level of an electron shell.
Step 2: For n=2, we need to find the types of orbitals available in this shell.
Step 3: The types of orbitals are s, p, d, and f. For n=2, we only have s and p orbitals.
Step 4: The s orbital can hold 1 orbital (1s).
Step 5: The p orbitals can hold 3 orbitals (2p).
Step 6: Add the number of orbitals: 1 (from 1s) + 3 (from 2p) = 4 orbitals total.
Step 7: Conclude that the total number of orbitals in the n=2 shell is 4.
