Category: Energy Levels

Atoms form the fundamental building blocks of all matter. Every solid, liquid, gas, and plasma that we observe in the universe is composed of atoms. Despite their minuscule size, atoms have an intricate internal structure consisting of a dense nucleus surrounded by electrons that occupy distinct energy levels. These energy levels are often described using…

Inside every atom, there are three main subatomic particles: protons, neutrons, and electrons. The protons and neutrons are tightly packed in the nucleus at the center of the atom,…
