All matter around us is made up about one hundred chemical elements.
Each chemical element is defined by the amount of protons in its nucleus.
The creator of the periodic table, Dmitri Mendeleev, in 1869 began collecting and sorting known properties of elements, like he was playing a game, while traveling by train. He noticed that there were groups of elements that exhibited similar properties.
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack)
You can visit The Royal Society of Chemistry´s interactive periodic tabel.
You can listen to podcasts, watch videos, and study data trends across the periodic table.
HOW DO ATOMS COMBINE?
Atoms, in a sense, are tied together to form molecules. The atoms of molecules are linked together through a reaction known as chemical bonding. A chemical bond is a force that holds atoms together.
Atoms in simple substances are organized in three ways:
Single atoms.
Large clusters.
Molecules.
Compound are made up of different types of atoms:
Molecules.
Clusters of ions with different charges:
An important clue to the understanding of the driving force for chemical bonding was the discovery of the noble gases and their apparently inert chemical behavior. Elements tend to attain this configuration of completely filled outer shells in order to gain stability.
