All atoms are made of three smaller particles called protons, neutrons and electrons. The protons and neutrons clump together at the center of an atom and the electrons orbit far away. Atoms can be combined to form molecules through chemical reactions.
To better understand atomic structure…
LET’S BREAK IT DOWN!
The center of the atom, often referred to as the nucleus, is made up of protons and neutrons. The protons are positively charged, while the neutrons don’t have a charge. Orbiting around the outside of the atom at a tremendous speed and distance are electrons. Electrons are the smallest of the three subatomic particles and have a negative charge. Empty space is found between the atomic nucleus and electrons.
