Question
Based on the postulates of Bohr’s atomic model, which of the following is incorrect
- The energy levels of electrons are called orbits
- When energy is observed, electrons jump from lower energy level to higher energy level.
- When an electron is observed, e lectrons jump from higher energy level to lower energy level.
- Each orbital is associated with definite amount.
Hint:
Electrons won't jump from higher energy level to lower energy level when it gets absorbed, so the statement is incorrect.
The correct answer is: When energy is observed, electrons jump from lower energy level to higher energy level.
- Bohr's theory states that electrons jump from higher energy level to lower energy level when it gets absorbed.
- The theory explains that the electrons are distributed in energy levels called orbits.
- Each orbit has definite energy in it.
