Question

What is an electron transition? A As electrons transition to other subatomic particles, such as protons and neutrons. B As electrons gain and lose energy and move between orbitals. C As electrons increase their kinetic speed within their orbital. D As electrons gain or lose negative charge.

Answer 1

The correct answer is **B**: "As electrons gain and lose energy and move between orbitals."

Electron transitions refer to the process where an electron moves between different energy levels (or orbitals) within an atom, typically as a result of absorbing or emitting energy, such as in the form of photons.
