Silicon Life Forms

The German scientist, Julius Scheiner was most likely the first person to realise there was a possibility of silicon being a basis of life. This idea was then grapsed by the british scientist James Reynolds in 1893. he then pointed out that its molecular integrity withheld in high temperatures which might allow life to exist at very high temperatures. Silicon seems promising when it comes to being the basis of life, but when the topic is researched futher. Carbon, when it is oxidized during the respiratory process, it becomes the gas carbon didoxide which allows it be released easily out of a body. When Silicone is oxidised, it has a reaction in which the product of it is a solid….

Old and Modern Perodic Table

PERIODIC TABLE PERIODIC TABLE Charles Janet developed the periodic table in 1928. How the periodic table is organized: Charles Janet’s periodic table was organized according all elements that had been discovering before 1928 according to the orbital filling. It also structures the electrons in ascending atomic order Describe the information the periodic table contains: DISADVANTAGE: * The periodic table has a rough tarnation from metal to none-metal. DISADVANTAGE: * The periodic table has a rough tarnation from metal to none-metal. ADVANTAGES: * Janet’s periodic table was helpful for writing electrons configurations. * The periodic table was easier to read. * It sectioned off none metal and metal ADVANTAGES: * Janet’s periodic table was helpful for writing electrons configurations. * The…
