Question

10 what produces electromagnetic radiation? a electrons changing energy levels b electrons bonding with other atoms c electrons leaving the atomic nucleus d electrons becoming protons or neutrons

Explanation:

When electrons change energy levels in an atom, they emit or absorb electromagnetic radiation. Electron - bonding is related to chemical reactions, electrons don't leave the atomic nucleus in the context of producing EM radiation in normal atomic processes, and electrons don't become protons or neutrons in the process of producing EM radiation.

Answer:

A. Electrons changing energy levels
