Question

What can scientists measure to provide evidence that electrons can move from one energy level to another

Answer 1

An electron will jump to a higher energy level when excited by an external energy gain such as a large heat increase or the presence of an electrical field, or collision with another electron.

evidence do Scientists have that electrons can move from one energy level to another? Light. Scientists can measure the energy gained when electrons absorb energy and move to higher energy levels. ... An electron cloud is a visual model of the most likely locations of the electrons in the atom.

Answer 2

recording the wavelength of light

Step-by-step explanation:

When an appropriate measure of energy say in the form of light of a certain wavelength, is supplied, electrons have a tendency to absorb the energy and get excited to a higher energy level. Conversely, if an electron is already at a higher energy state it will emit energy in the form of light (or heat) and return to a more stable lower energy state.
