Question

According to the Bohr's model, angular momentum of n^th orbit is given by ________
1. \({nh \over 2 \pi}\)
2. \({h \over 2 n \pi}\)
3. \({h \over \pi}\)
4. None of the above

Answer 1

Correct Answer - Option 1 : \({nh \over 2 \pi}\)
CONCEPT:

• Every electron revolves around the nucleus in the orbits.
• The nucleus is positively charged and the electrons that revolve around the nucleus are negatively charged, so they attract each other.
• Bohr was the scientist who gave an explanation of Hydrogen.
• Bohr's model of hydrogen is based on the assumption that electrons travel in specific shells, or orbits, around the nucleus.
• According to Bohr's quantization condition, angular momentum will be multiple of \( {h\over 2\pi}\)

​Angular momentum (L) = nh/2π

where n is the orbit number, h is Plank's constant.​

EXPLANATION:

• According to Bohr's quantization condition, angular momentum will be multiple of \( {h\over 2\pi}\)

​Angular momentum (L) = nh/2π

where n is the orbit number (N = 1, 2, 3.....), h is Plank's constant.​

Hence the correct answer is option 1.
