Question

n=- — n=4 - n-3 + In the Bohr model of the hydrogen atom, the electron occupies distinct energy states. n-2 "One transition between energy states of the hydrogen atom is represented by the picture on the left. Niels Bohr n-1 1. In this transition an electron moves from the n= level to the n= level. 2. Energy is A. Absorbed B. Emitted in this process. A. Closer to 3. The electron moves R B. Further from the nucleus.

Answer 1

Answer Sheet:

According to the bohr's model the energy state represent by principal quantum number i.e n

( where n = 1,2,3,4,.........).

The energy increases with increase n . The given transition in the question is represent the electron transition from n=4 level to n=1. Since this transition occur from higher energy to lower energy .So in this transition the energy is emitted . Also since the electron transition higher energy to lower energy that means the electron moves closer to the nucleus because the energy decreases when electron moves towards the nucleus.

So

1. In this transition an electron moves from the n= 4 level to n= 1 level

B. 2. Energy is Emitted in this process.

A. 3. The electron moves Closer to the nucleus.
