Atomic Structure Atoms are the basic building blocks of everything around us. They come in different kinds, called elements, but each atom shares certain characteristics in common.All atoms have a dense central core called the atomic nucleus.Forming the nucleus are two kinds of particles: protons, which have a positive electrical charge, and neutrons, which have no charge.
The atom is the basic unit of matter.It is the smallest thing that can have a chemical property.There are many different types of atoms, each with its own name, atomic mass and size. These different atoms are called chemical elements.The chemical elements are organized on the periodic table.
