Question

What is the energy in joules required to shift the electron of the hydrogen atom from n1 ti n5 orbir?

Answer 1

Answer:

Ground state energy (E1) = – 2.18 × 10–11 ergs (given)

= –2.18 × 10–11 × 10–7 J

= – 2.18 × 10–18 J

Also the energy required to shift the electron from n = 1 to n = 5 is given as ΔE = E5 – E1

The expression for the energy of hydrogen of electron is

En = -2π2me4Z2/n2h2

Where m= mass of electrons

Z=atomic mass of atom

e = charge of electron

h = planck’s constant

Now putting the values in the equation ΔE = E5 – E1 we get
