How many subshells are in the 𝑛=3 shell? & How many orbitals are in the 𝑛=3 shell? & What is the maximum number of electrons in the 𝑛=3 shell?

Question

How many subshells are in the 𝑛=3 shell?

1. ? Subshells

How many orbitals are in the 𝑛=3 shell?

1. ? Orbitals

What is the maximum number of electrons in the 𝑛=3 shell?

1. ? Electrons

Answer 1

1). When n = 3, there are THREE subshells:

s, p, d

2). When n = 3, there are NINE orbitals:

1 s orbital + 3 p orbitals + 5 d orbitals

3). The maximum number of electrons in the n = 3 shell is 18 electrons:

2 electrons in the s + 6 electrons in the p + 10 electrons in the d = 18 elelctrons
