Even though Mendeleev''s periodic table was based on atomic weight, he was able to predict the discovery and properties of certain elements. As during his time only around half of the elements known to us now were known, and most of the information known about the elements were inaccurate. Mendeleev''s Periodic Table was published in the German Journal of chemistry in 1869.

The millions of different chemical compounds that make up everything on Earth are composed of 118 elements that bond together in different ways. This module explores two common types of chemical bonds: covalent and ionic. The module presents chemical bonding on a sliding scale from pure covalent to pure ionic, depending on differences in the electronegativity of the bonding atoms.

Chlorine was discovered in 1774 by Carl Wilhelm Scheele. He obtained it through the reaction of the mineral pyrolusite (manganese dioxide, MnO 2) with hydrochloric acid (HCl, then known as muriatic acid). Scheele thought the resulting gas contained oxygen. Sir Humphry Davy proposed and confirmed chlorine to be an element in 1810, and he also ...
