Electron

 Electron revolves around the nucleus of an atom 


The electron is a subatomic particle, whose electric charge is negative one elementary charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.

Antiparticle

 Antiparticle, subatomic particle having the same mass as one of the particles of ordinary matter but opposite electric charge and magnetic moment. Thus, the positron (positively charged electron) is the antiparticle of the negatively charged electron. Every type of particle has a corresponding antiparticle, for example; the positron is the antiparticle of the electron. the antiproton is the antiparticle of the proton. the antineutron is the antiparticle of the neutron. the antineutrino is the antiparticle of the neutrino.

Plastics and FAQ

 Plastics is the term commonly used to describe a wide range of synthetic or semi-synthetic materials that are used in a huge and growing range of applications. The raw materials used to produce plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil. FAQ  What are plastics made of? Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. What are the 7 types of plastic? The Basics On 7 Common Types of Plastic 1) Polyethylene Terephthalate (PET or PETE) 2) High-Density Polyethylene (HDPE) 3) Polyvinyl Chloride (PVC or Vinyl) 4) Low-Density Polyethylene (LDPE) 5) Polypropylene (PP) 6) Polystyrene (PS or Styrofoam) 7) Other.

Vaquita(Most endangered animal)

Image
  The vaquita is a species of porpoise endemic to the northern end of the Gulf of California in Baja California, Mexico. Averaging 150 cm or 140 cm in length, it is the smallest of all living cetaceans. Vaquita, the world's rarest marine mammal, is on the edge of extinction. The plight of cetaceans—whales, dolphins, and porpoises—as a whole is exemplified by the rapid decline of the vaquita in Mexico, with about 10 individuals remaining. This little porpoise wasn't discovered until 1958 and a little over half a century later, we are on the brink of losing them forever. Vaquita are often caught and drowned in gillnets used by illegal fishing operations in marine protected areas within Mexico's Gulf of California. The population has dropped drastically in the last few years. The vaquita has a large dark ring around its eyes and dark patches on its lips that form a thin line from the mouth to the pectoral fins. Its top—the dorsal surface—is dark gray, its sides are pale gray, ...
