Textbook Problem

Find the radius of a hydrogen atom in the n = 2 state according to Bohr's theory.

To determine

The radius of a hydrogen atom in then=2 state.

Explanation

Given Data:

A hydrogen atom in then=2 state

Formula Used:

Radius of atomic orbit is given as

rB=n2aBz

WhererB= Radius of orbit

n= Energy level

aB= Bohr's radius

z= Number of proton

Calculation:

Given thatn=2

  z=1

  aB=0.529×1010m

Substituting the above values, radius of hydrogen atom is calculated as

  rB=(2)2(0
