PERIODIC TABLE OF ELEMENTS
Here are a collection of mnemonic sentences supplied by Neville Holmes (6/00) of Australia for the elements in the first four periods of the chemical Periodic Table.
Hydrogen - Periodic Table. Hydrogen is a 1. Chemical element in the periodic table of elements. It has 1 protons and 1 electrons in the atomic structure. The chemical symbol for Hydrogen is H. Periodic Table of Elements: The elements are arranged horizontally in order of increasing atomic weights. Those beneath each other have similar properties. Hydrogen (Atomic No.1) is omitted as it is unlike any other element. O IA IIA IIIA IVA VA VIA VIIA 9 10 11; 2 He helium: 3 Li lithium: 4 Be beryllium: 5 B boron: 6 C carbon: 7 N nitrogen: 8.
Periodic Table of Elements - The Periodic Table is a tabular arrangement of the chemical elements, organized on the basis of their atomic numbers (numbers of protons in the nucleus), electron configurations, and recurring chemical properties. Helium is extensively used for filling balloons as it is a much safer gas than hydrogen. One of the recent largest uses for helium has been for pressuring liquid fuel rockets. A Saturn booster, like the type used on the Apollo lunar missions, required about 13 million ft 3 of helium for a firing, plus more for checkouts. Forget 10 Downing Street or 1600 Pennsylvania Avenue, the most prestigious address in the universe is number one in the periodic table, hydrogen. In science, simplicity and beauty are often equated - and that makes hydrogen as beautiful as they come, a single proton and a lone electron making the most compact element in existence.

Where Do Hydrogen And Helium Come From
All matter consists of atoms of one or another element such as hydrogen (H) or oxygen (O), often combined into compounds (as in H2O=water). The elements are set in a Periodic Table in the order of their atomic weights (starting with hydrogen, the lightest) following Mendeleev's Periodic Law, which states that 'the properties of the elements are in periodic dependence upon their atomic weights' - in other words, elements either eight or ten places apart have many properties in common. See rare earths for the order of rare earth elements and rare gases for a mnemonic sentence governing the order of rare gases. For those completely unfamiliar with the Periodic Table itself, it is reproduced below in full.
