Question

calculate the five lowest energy levels of hydrogen atom​

Answer 1

Answer:

(n=1) is 13.6 eV this is your answer

Answer 2

The five lowest energy levels of hydrogen atom are calculated as shown:

• Electrons in atom are allowed to exist only in certain shells with certain energy levels.
• The energy level for an atom depends on its atomic number and principle quantum number.
• Following Bohr's theory, energy level for hydrogen like atoms is calculated as shown:

$- 13.6 \frac{ {z}^{2} }{ {n}^{2} } ev$

where z= atomic number of atom

n = shell number

Substituting values as shown:

• For hydrogen like atom, z= 1

• For n= 1, Energy= -13.6eV
• For n=2, Energy = -3.4eV
• For n=3, Energy= -1.51eV
• For n=4, Energy = -0.85eV
• For n=5, Energy= -0.54eV

(To convert eV to Joules, multiply the quantity with 1.602x10^-19)
