Question

In the 1920s, Heisenberg, de Broglie and Schrodinger developed what is now called quantum mechanics. Consider the following statements with regard to this model:

a. The position of an electron can be exactly found and measured.
b. With the use of modern instruments, scientists can watch an electron move from point to point in its orbit.
c. Energy levels in quantum mechanics are not limited to certain discrete values, but are actually continuous.
d. Electrons get excited to high energy levels when they absorb energy, and can emit light when they relax.

Which of the above statements is/are true?

Answer 1

d. Electrons get excited to high energy levels when they absorb energy, and can emit light when they relax.

Step-by-step explanation:

Quantum mechanics is a branch of Physics that describes and explains an expression for subatomic particles and their interactions. Understanding of the behavior of subatomic particles, explains the behavior and observations in physical systems. This model relates matter and energy.

An atom consists of electrons orbiting the nucleus with the electrons placed in the quantised energy level or orbits. When an electron absorbs energy, it gets excited and jump to the equivalent energy level with respect to the energy absorbed. On de-excitation, it falls to its initail energy level with a release of photon.
