Chapter 36: Problem 2

A friend who hasn't studied physics asks you the size of a hydrogen atom. How do you answer?

Short Answer

Expert verified
The size of a hydrogen atom is approximately 0.529 脜ngstroms or 52.9 picometers, defined as the Bohr radius.

Step by step solution

01

Understand what is the Bohr radius

The hydrogen atom is best described using the quantum mechanical model. The Bohr radius, named after Niels Bohr who proposed the quantum mechanical model of the atom, is the most likely distance between the proton and electron in a hydrogen atom.
02

Recall the value of the Bohr radius

The value of the Bohr radius is well documented and is approximately 0.529 脜ngstroms (or 52.9 picometers), where one 脜ngstrom equals \(1 \times 10^{-10}\) meters.

How many quantum numbers are required to specify fully the state of a hydrogen atom?

The electron is a spin- \(\frac{1}{2}\) particle. Does this mean the electron's intrinsic angular momentum is \(\frac{1}{2} \hbar ?\) Explain.

Suppose you put five electrons into an infinite square well of width \(L .\) Find an expression for the minimum energy of this system, consistent with the exclusion principle.

Find (a) the energy and (b) the magnitude of the orbital angular momentum for an electron in the \(5 d\) state of hydrogen.

An infinite square well contains nine electrons. Find the energy of the highest-energy electron in terms of the ground-state energy \(E_{1}.\)
