Lesson: Periodic Table of Elements

There is a natural order of elements sequenced on the period table of elements, which combine to form every compound in existence. Each element has a unique Atomic Weight: Hydrogen = 1 and Oxygen = 7. The unit of measure for atomic weight is called mole for molecular. The table is exquisitely laid out and harmonically adheres to the Law of Octaves, proving that properties of elements periodically repeat when arranged by Atomic Number; that is why it is know as the Periodic Table of Elements.
The atomic number for gold is 79 and its symbol is Au. The atomic number means that gold is comprised of 79 electrons and 79 protons. The molecular weight of gold is 196.96657 rounded to 197. This theory was not respected until the acceptance of Valence Bonding Theory and the Octet Theory of Chemical Bonding. Proof of each element’s unique visual signature arrived with the introduction of Spectroscopy.

Centered on this methodic masterpiece, between the heavy metals on the left side of the table and the noble gases on the right, lie the semiconductors used to control the processes of computers. Silicon, written Si, is one of the first elements used for this purpose. The area where the majority of computer chips are manufactured in the US is called Silicon Valley, California.

Although co-created by Antoine-Laurent and Stanislao Cannizzaro, and published in 1869; Russian born Dmitri Mendeleev is known as the father of the Periodic Table. Mendelevium, written Md, is a radioactive rare earth element with an Atomic Number of 101 and Atomic Weight of 258; and is named for Mr. Mendeleev. Also, Mendelevium is the name of an impact crater on the Dark Side of the Moon. Mendeleev did an excellent job of identifying and saving space for with atomic numbers for elements not known at that time; and he also, wrote the Law of Periodicity.

Robert Bunson, who the Bunson Burner is named for; heated the elements and discovered that copper burns green, strontium burns red and potassium burns blue. This science is demonstrated in the spectacular firework displays that we enjoy.
