Question

How many orbitals are in the 3s subshell?

Answer 1

The 3s subshell contains one orbital. In the n=3 shell, there are three subshells: 3s, 3p, and 3d, with 3p having three orbitals and 3d having five orbitals.

Step-by-step explanation:

The number of orbitals in the 3s subshell is one. Subshells are denoted by their angular momentum quantum number l, and s subshells have an l value of 0. Since each s subshell can contain only one spherical orbital, regardless of the principal quantum number n, the 3s subshell, therefore, contains a single orbital. In a principal shell with n = 3, there are three subshells: the 3s, 3p, and 3d subshells. The 3p subshell contains three orbitals, and the 3d subshell contains five orbitals, as the number of orbitals in a given subshell increases with increasing values of l.

Answer 2

Orbitals are three regions near the nucleus where electrons are found. Each orbital has a specific energy corresponding to it. s orbitals are spherical and a number is associated with it called the principal quantum number. Examples are 1s, 2s, 3s, 4s, 5s and 6s. The s orbitals occurs as a single orbital.
