desire‚ views‚ precepts and vows‚ and to the doctrine of the self. Without attachment to these worldly things‚ and by following the Noble Eightfold Path‚ we can achieve nirvana. If this enlightened state of mind is not achieved by the end of life‚ we continue the cycle and are again reincarnated into a new body. Continuing the cycle‚ our soul will remain and seek out through the need of attachment‚ attachment to a new body and a new life‚ a process otherwise known as the doctrine of the self.

The Periodic Table is a chart which arranges the chemical elements in a useful‚ logical manner. Elements are listed in order of increasing atomic number‚ lined up so that elements which exhibit similar properties are arranged in the same row or column as each other. Elements are also arranged in different families and periods based on similar characteristics. Also the grouping of elements into into subcategories Metals‚ Nonmetals‚ and Metalloids. The Periodic Table is one of the most useful tools

the behavior of Gases Matter: Occupies space‚ has a mass‚ exists in 3 physical states namely solids‚ liquids & gases; composed of particles. Solid: have fixed shape‚ fixed volume. Liquid: takes shape of part of container below liquid level. No fixed shape‚ has fixed volume‚ flow easily. Gas: when collected into vessels occupies all space inside vessel‚ takes shape of container‚ no fixed shape or volume. Arrangement of particles in solids‚ liquids & gases • Attractive

William Ramsay William Ramsay was born on the second of October‚ in the year 1852. William‚ and his parents‚ William and Catherine‚ lived in Glasgow‚ Scotland. William Ramsay performed his work in his native town‚ until 1870 when he went to Tübingen and earned his doctorate in 1872. When returned to Scotland later that year‚ he became an assistant chemist at the Anderson College in Glasgow. Eight years later‚ he was appointed principal and professor of chemistry at London University‚ which

number is 10‚ protons‚ electrons are 10‚ 10 neutrons and its symbol is Ne. Neon is a noble gas. The period of neon is 2‚ and the group is 18. Neon is very rare on earth even though it’s very common element in the universe. In the earth’s atmosphere‚ neon only comprises 0.0018 percent of the volume. On the earth‚ neon is always present as a gas. Neon has three stable isotopes‚ and it’s the second lightest noble gas‚ after helium. Two different types of neon are commonly used in the world.

Objectives 1-Describe the periodic trend in atomic radius and relate it to atomic structure 2- Describe the periodic trend in electronegativity and relate it to atomic structure Did you know? There are atoms with no electronegativity because electro negativity refers to the attraction of atoms of electrons in a compound; elements that do not form are assigned no electronegativity values. Atomic Radius ≠ Ionization Energy As you move from left to right on the periodic table‚ the number of

PICTURE (http://images-of-elements.com/xenon-2.jpg) 2. DESCRIPTION OF XENON The name originates from the Greek word ’xenon’ meaning the stranger. (http://www.elementalmatter.info/element-xenon.htm) Xenon is the fifth member of the noble gases‚ and makes up one part of a twenty millionth of the atmosphere. It is colorless‚ tasteless‚ odorless‚ and a non metal element. When put in a vacuum tube‚ it creates a bright blue glow because of the electrical discharge. Xenon has the following

most of us encounter neon on a daily basis as opposed to other elements such as pure gold or silver. Our world is much more colorful as a result of neon. The symbol of Neon is Ne. It is also in group 18 of the periodic table so it is classified as a noble gas. The atomic number of Neon is 10. Neon is the 10th element on the periodic table. This essay will discuss the many uses of Neon and its origins as well as the scientific aspect of the element such as its electron configuration‚ physical properties

is the planet Superman is from‚ but it is actually a chemical element. Krypton is one of the rarest gases on Earth which makes it very expensive. It can also be found in Mars’s atmosphere‚ but only makes up 0.3 parts of a million. Krypton was discovered in 1898 by Morris Travers and Sir William Ramsey. It was named after the Greek word‚ kryptos‚ which means “hidden”. The basic facts: Noble gases carry the trait of not reacting with many elements and Krypton is classified in this group. It is located
