Marie‚ as well as her husband‚ went on to discover two new elements recently unknown to man‚ those being polonium and radium. Marie became the first woman to win a Nobel Prize for her scientific achievements‚ but the awards did not stop there. She later became the first person ever to win a second Nobel Prize.

Did you know that for every cigarette you smoke you can lose eleven minutes off your life? Smoking can not only leave you with long term affects you may not be able to get rid of but it will leave you poor and maybe dead. Mankind first came in touch with tobacco approximately eighteen thousand years ago‚ when migrant Asiatic people first intersected the Bering Strait and extended across the continents today known as the Americas‚ where tobacco is native (Gately ‚2001).

It is so fitting that 2011 is the centenary year for the award of Nobel Prize to Marie Curie for her discovery of Radium and Polonium. Also this is the 150th birth anniversary of Dr. P .C Roy.

Marie Curie How were the elements of the periodic table discovered? Who discovered them? These are questions that some people may ask. Marie Curie and her husband‚ Pierre Curie‚ were two scientists that discovered two elements of the periodic table‚ polonium and radium. She and her husband worked all of their lives to understand radium and radioactivity. When something is radioactive‚ it produces radiation‚ which is moving subatomic particles.The interesting thing is‚ that radium‚ what Marie Curie discovered

Wilhelm Röntgen‚ a mechanical engineer and physicist in Germany on November 8‚ 1895 was working in a lab when he had saw some strange fluorescence coming from a table. On the table he found a tube covered in opaque black paper which he was using to study rays. He had concluded that the fluorescence that had gone through the opaque paper was caused by rays. Henri Becquerel used Roentgen’s discovery of rays through the fluorescence some materials produce. Becquerel did a experiment surrounding several

Cancer has had an increasing impact in our world and the lives of others. The factors of this disease are all around us. Cancer can be caused by dangerous environmental substances called carcinogens‚ which are substances that are known to cause cancer. Overall‚ this disease is caused by changes in genes and it alters the way our cells function. Exposure to particular environmental substances can cause damage to your DNA. Some of these exposures are things such as chemicals‚ tobacco smoke‚ or even

INDOOR AIR QUALITY (PUBLIC AWARENESS) Indoor air is often considered safe and free from pollutants. But most people have the greatest contact with toxic pollutants not outside but inside their homes and offices. The modern consumer products like air fresheners‚ cleaning compounds‚ moth repellants‚ cigarettes‚ toilet disinfectants or deodorizers are the most common sources that laden the indoor air with toxic pollutants without anyone even suspecting them or their potential.

Chemical Prperties of Metals Most metals are chemically reactive‚ reacting with oxygen in the air to form oxides over changing timescales (for example iron rusts over years and potassium burns in seconds). The alkali metals react quickest followed by the alkaline earth metals‚ found in the leftmost two groups of the periodic table. Examples: 4Na + O2 → 2Na2O (sodium oxide) 2Ca + O2 → 2CaO (calcium oxide) 4Al + 3O2 → 2Al2O3 (aluminium oxide) The transition metals take much longer to
