# What Are the Quantum Numbers for a 3d State in Hydrogen?

• giffary
In summary, atomic physics is a branch of physics that focuses on the behavior and properties of atoms. It has many real-world applications, such as in the development of atomic clocks and medical imaging technology. The Bohr model of the atom describes the structure of an atom as a small, positively charged nucleus surrounded by orbiting electrons at specific energy levels. Atomic physics is closely related to quantum mechanics, which provides the mathematical framework for understanding the behavior of atoms and their constituent particles. Some current challenges in atomic physics research include understanding dark matter, developing new methods for controlling atoms, and exploring quantum computing.

## Homework Statement

Find all possible values of L, Lz, and θ for an electron in a 3d state of hydrogen.

I confuse it long time..

Do you not have any resource to work from or a textbook? Usually you have to offer some attempt at the solution.

L = $$\sqrt{6h}$$

Lz = -2h, -h, h or 2h

but I don't know its solution.

Ask yourself, what do the 3 and d mean for a 3d state, what are the values of l and n for a 3d state of H?

## 1. What is atomic physics?

Atomic physics is the branch of physics that studies the behavior and properties of atoms, including their structure, interactions, and energy levels.

## 2. What are some real-world applications of atomic physics?

Atomic physics has many practical applications, such as in the development of atomic clocks, nuclear power, medical imaging technology, and semiconductor devices.

## 3. What is the Bohr model of the atom?

The Bohr model of the atom, proposed by Niels Bohr in 1913, describes the structure of an atom as a small, positively charged nucleus surrounded by orbiting electrons at specific energy levels.

## 4. How does atomic physics relate to quantum mechanics?

Atomic physics is closely related to quantum mechanics, as it involves the study of the behavior of particles at the atomic and subatomic level. Quantum mechanics provides the mathematical framework for understanding the behavior of atoms and their constituent particles.

## 5. What are the current challenges in atomic physics research?

Some current challenges in atomic physics research include understanding the properties of dark matter, developing new methods for controlling and manipulating atoms, and exploring the possibilities of quantum computing.
