Question

Find out the correct statement about the energy of Electrons​

Answer 1

Answer:

The correct answer is D. Since a β-decay is always accompanied by an anti-neutrino. Hence (a) is incorrect which only leaves us with option D.

Answer 2

Answer:

The energy of an electron is of the same order of magnitude (is in the same range) as the energy of light. The lines in the spectrum of an element represent changes in the energy of electrons within the atoms of that element.
