what is particulate matter? particulate matter, or pm, isn’t just one contaminant or pollutant. it’s a range of particles of dust, dirt, and liquids that become suspended in the air. some of these are large enough to see, like smoke, smog, or soot, but the most harmful are smaller...
Orbiting the nucleus, we find the tiny, negatively charged particles known as electrons.Answer and Explanation: The two subatomic particles that make up the mass of an atom are protons and neutrons. Each of these has a mass of one AMU, or atomic mass unit...Become a member and unlock all...
Particle accelerators are devices that speed up the particles that make up all matter in the universe and collide them together or into a target. This allows scientists to study those particles and the forces that shape them. Specifically, particle accelerators speed up charged particles. These are...
Particle physics is a branch of physics that studies the particles that make up matter. So this branch of physics tries to understand matter at its most fundamental level and how matter behaves at that level. It also tries to understand how matter interacts and turns from one form to another...

Introduction We live surrounded by environmental hazards including toxic compounds in air, ...
Sterile neutrinos are another candidate.Neutrinosare particles that don't make up regular matter. A river of neutrinos streams from thesun, but because they rarely interact with normal matter, they pass throughEarthand its inhabitants. There are three known types of neutrinos; a fourth, the steri...
or others make out some dirt in the air and that is air pullution One type of air pollution is the release of particles into the air from burning fuel for energy. These include *** og acid rain the greenhouse effect and "holes" in the ozone layer.空气污染=air pollution ...
However, dark matter is harder to study than even that because it does not come conveniently clumped into super-dense balls likestarsand black holes. (That would be far too easy.) Instead, the primary theory of dark matter says that it is made of hypothetical particles called Weakly Interacti...
The Standard Model of particle physics includes the matter particles (quarks and leptons), the force carrying particles (bosons), and the Higgs boson. There are six "flavors" of quark: up, down, charm, strange, top, and bottom. Each also has an antiparticle, called an antiquark. Quarks...
To fully understand matter let's look at the atom. It is now generally accepted that atoms are made up of three particles called neutrons, protons, and electrons. The neutrons and protons are found in the nucleus (center) of the atom and the electrons reside in a shell surrounding the nuc...
