How many orbitals are there in an energy level? What are the n and ml quantum numbers corresponding to the 3s orbital? In what specific subshell will an electron having the quantum numbers n=3, l=1, and ml=1 be found? Write the spdf and orbital diagram, electron configuration of an element with Z=25 and determine the group, period, and block of the element.
Understand the Problem
The question is part of a chemistry worksheet that contains multiple inquiries related to atomic structure, electron configurations, and fundamental properties of elements. It addresses concepts such as quantum numbers, the properties of protons, and the electromagnetic spectrum.
Answer
n=3 has 9 orbitals. 3s: n=3, ml=0. 3p subshell: n=3, l=1, ml=1. Z=25: [Ar] 3d⁵ 4s², group 7, period 4, d-block.
The energy level with n=3 has nine orbitals. The 3s orbital has n=3 and ml=0. An electron with n=3, l=1, and ml=1 is in the 3p subshell. The electron configuration of Z=25 is [Ar] 3d^5 4s^2, placing it in group 7, period 4, and the d-block.
Answer for screen readers
The energy level with n=3 has nine orbitals. The 3s orbital has n=3 and ml=0. An electron with n=3, l=1, and ml=1 is in the 3p subshell. The electron configuration of Z=25 is [Ar] 3d^5 4s^2, placing it in group 7, period 4, and the d-block.
More Information
Manganese is a transition metal with important uses in steel production due to its properties. The d-block elements are known for their ability to form various oxidation states.
Tips
A common mistake is counting orbitals incorrectly; remember that each principal energy level n can hold n^2 orbitals.
