The particle physics of you
Most of the Universe consists of matter and energy. Energy is the capacity to do work. Matter has mass and occupies space. All matter is composed of basic elements that cannot be broken down to substances with different chemical or physical properties. Elements are substances consisting of one type of atom , for example Carbon atoms make up diamond, and also graphite. Pure 24K gold is composed of only one type of atom, gold atoms.
All matter in the universe was formed in one explosive event In the American astronomer Edwin Hubble discovered that the distances to far-away galaxies were proportional to their redshifts. Redshift occurs when a light source moves away from its observer: the light's apparent wavelength is stretched via the Doppler effect towards the red part of the spectrum. If galaxies are moving away from us, reasoned Hubble, then at some time in the past, they must have been clustered close together. Subsequent calculations have dated this Big Bang to approximately In two teams of astronomers working independently at Berkeley, California observed that supernovae — exploding stars — were moving away from Earth at an accelerating rate.

Reference Article: Facts about atoms, the building blocks of matter.
An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. Every solid , liquid , gas , and plasma is composed of neutral or ionized atoms. This is due to quantum effects. Current atomic models now use quantum principles to better explain and predict this behavior. Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons.
Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons , electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom, called the nucleus , and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.
