The definition of Atom.
Continue ReadingSolid
A solid is a state of matter where the atoms are tightly packed and held in place by strong interatomic forces. Solids have a definite shape and volume and are much more complex to compress than liquids or gases. As a result, most known materials are solids. The three most common states of matter are… Read More

A neutron is a subatomic particle, symbol n or n0, with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, and each has an associated electron orbiting it outside the nucleus (forming an… Read More
Continue ReadingProton Overview
A proton is a subatomic particle, symbol p or p+, with a unitary electric charge of +1e. The rest mass of the proton is 1.6726231×10−27 kg, about 1836 times that of an electron. Protons and neutrons are collectively referred to as “nucleons”. Since 1918, protons have been known to be positively charged particles found in… Read More
