Chemistry Question on Structure of atom
In Hydrozen atom, energy of first excited state is – 3.4 eV. Then find out KE of same orbit of Hydrogen atom
A
3.4 eV
B
6.8 eV
C
– 13.6 eV
D
13.6 eV
Answer
3.4 eV
Explanation
Solution
The correct option is (A) : 3.4 eV
Kinetic energy is the only kind of energy present in an excited state. Thus, the KE of a H atom is TE+3.4 eV.
