Fundamentals of Chemistry:
The fundamentals of Chemistry is basics to the Periodic Table, chemical states, equilibria, acid/bases, reduction/ oxidation reaction, kinetics, bonding, among other sections of chemistry.
Each chemical molecule in the universe has basic properties which distinguish it from all of the other chemical substance. Although each is unique, the elements may be still grouped by their commonalities in a needful and meaningful way. The periodic table sets the elements by properties.
Each element has its own properties and these properties make up groups and rows. There are eighteen families or groups or columns on the periodic table. Each one show how many electrons are attached to the elements and relate to how many valence electrons are present. Electrons are negatively charged sub atomic molecules that revolve around the nucleus of the element. Valence electrons are that are on the outside of the atom. There are seven rows (or horizontal rows) that define electron shells, but more details on electron shells will be defined in advanced pages.
