  • Diamonds Are Forever

    Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?

  • Creating Malachite egg

    One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

  • Use of diamonds

    Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...

  • What are Compound Microscopes?

    Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

  • Protein Design: Automated protein discovery and synthesis

    In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.

Heterogeneous Mixture

A mixture that does not have uniform composition and properties throughout.

Beta Particle

Electron emitted from the nucleus when a neuton decays to a proton and an electron.

Formula Weight

The mass of one formula unit of a substance in atomic mass units.

 

Electron

A subatomic particle having a mass of 0.00054858 amu and a charge of 1-.

Stoichiometry

Description of the quantitative relationships among elements and compounds as they undergo chemical changes.

Valence Electrons

Outermost electrons of atoms, usually those involved in bonding.

Bonding Orbital

A molecular orbit lower in energy than any of the atomic orbitals from which it is derived, lends stability to a molecule or ion when populated with electron.

Gamma Ray

High energy electromagnetic radiation. A highly penetrating type of nuclear radiation similar to x-ray radiation, except that it comes from within the nucleus of an atom and has a higher energy. Energywise, very similar to cosmic ray except that cosmic rays originate from outer space.

Levorotatory

Refers to an optically active substance that rotates the plane of plane polarized light counterclockwise, also called levo.

Hydride

A binary compound of hydrogen.
