Essay on Physics The Radium Element - 527 Words

An element is a substance that is made entirely from one type of atom. Each element has its own kind of atom. There are three major parts to an atom, protons, neutrons and electrons. Each element is found on the periodic table. The periodic table tells us the elements, element name, atomic number, atomic mass and symbol. The element radium has 88 protons, 138 neutrons and 88 electrons. Its atomic number is 88. The symbol for Radium is Ra and its atomic mass is 226. Radium’s melting point is 700 °C and its boiling point is 1140 °C. Radium is lustrous, soft, and intensely radioactive Radium, when in its pure metal form, is a slivery – white. However, it blackens when it is exposed to air. This element is a rock therefore it naturally occurs.†¦show more content†¦Not only does radium treat cancer but; when radium is mixed with zinc sulfide, radium forms a self-luminous paint used on the dials of watches, clocks, and other instruments. When it’s formed into self- luminous paint, it is a very bright green colour. Scientists also used this self- luminous paint in glow sticks, because of the bright green glowing colour. Radium could also produce cosmetics and toothpaste but has now been replaced by cobalt, because radium strongly radioactive and dangerous. Although Marie did pass away from radium, small amounts of radium turned into gas, in cancer medicines can save peoples lives. But now today’s radium is very limited and is only used in laboratories with trained scientists. Only very few scientists have a career with working around radi um. Also, miners because Radium is present in tiny amounts in seawater and in most of the earth’s rocks. Its chief sources are pitchblende and the ores of its mother element, uranium. In conclusion, radium is an element on the periodic table. It has 88 protons, 88 electrons and 138 neutrons. Marie Currie discovered it in 1898. She died from working with it because it was highly radioactive. It’s used for to make dials on watches, clocks and other instruments and it can treat cancer when turned into radon gas. Radium is a rock found in the earth’s rock and seawater. It is also very dangerous and can destroy living cells. Its chief sources are pitchblende and the ores of itsShow MoreRelatedEssay about Marie Curie851 Words   |  4 Pagesnbsp;nbsp;nbsp;nbsp;nbsp;Marie Curie(1867-1934) was a French physicist with many accomplishments in both physics and chemistry.
