Period 5 element

Phosphorus: General: Phosphorus is one of chemical elements of periodic table with atomic number 15 and atomic mass 30.9738 g/mol. Phosphorus is one of members of polyvalent non-metal of Nitrogen group and can be found in nature as some different allotropic format. Phosphorus can not be found free in nature since it’s so reactive and while it’s isolated and pure, it is clear and almost transparent. Phosphorus can be found in three common forms as white, red and black which their particular…

Group 1 Elements Referring to the table created from observing the characteristics of the three elements from group 1, Lithium, Sodium, and Potassium, we can see that they all share the appearance of being lustrous and metallic, with a silvery-white presentation, and it is also known that they are all alkali metals. It is also noticed that they are all soft metals easily cut with a knife rather than most metals such as calcium or iron. All three elements are stored within oil, with Sodium as an…

textbook. While making his textbook he needed a way to organize the elements so it was easier to understand. He put all the elements on notecards and started organizing them in a game he called chemical solitaire. He worked for three days straight completely focused. On the third night he fell asleep and had a dream where all the elements were falling into place. He woke up saying, “In a dream I saw a table where all the elements fell into place as required. Awakening, I immediately wrote it…

copper sulfate formed a salt, noting an acid-base reaction. In the process of the experiment bonds between two species of chemicals yielded the creation of products with similar bonding affiliations, which demonstrates a metathesis reaction. The elements of the compound basically interchange. The focus of the fifth cycle was to reform the copper. Zinc mesh was placed into the copper (II) sulfate, which yielded zinc sulfate and the recovery of copper. The balanced molecular equation was CuSO4…

Wouldn’t it be nice if you could change a simple worthless piece of junk into gold? I know I would love to. Alchemy is the ancient practice that’s shrouded in mystery and secrecy. Many believed only certain people were worthy of the knowledge of alchemy. When I was first introduced into the life of alchemy, my mind was clouded by what I was researching. I didn’t quite wrap my head around it but still at the same time I felt a deep sensation of excitement to learn more about alchemy; I began to…

back 2.6 million years ago and due to the Holocene period can accordingly be called the Age of Man (Quaternary Period, 2014). During the quaternary period fluctuations of the climate caused glaciers to advance from the poles and retreat with each cycle, carving and moulding the land (National Geographic, 2014). Over the past 800,000 years the planet has formed cyclical patterns, with ice ages lasting around 100,000 years followed by warm periods lasting 10,000-15,000 years. The last ice age…

Love Canal Sophie Albright The Love Canal tragedy, in 1942, caused conflict and stirred up arguments, socially, economically, and environmentally. Unwanted chemicals from various experiments and projects from different companies and groups were dumped at a waste site in Niagara Falls, New York, thinking the landfill would cause no harm. The chemicals were then, out of sight, out of mind. When the area was turned into a neighborhood, it then became evident those discarded…

Alchemists used to obsess over chrysopoeia, the transmutation of regular metals, such as copper, into gold. However, they were not aware at the time that copper and gold were two different atomic elements and instead believed them to be compounds. Thinking these metals could be changed chemically or physically in labs, alchemists pursued this dream to no advantage. Although it is not possible to change ordinary metals to gold through chemical reactions, physical reactions, radioactive decay, or…

as if the bright colors on the chart were generating warmth (energy) and that chart was an exhibit of the Periodic Table. For years, different people ventured to group elements by their chemical traits. However, Dmitri Ivanovich Mendeleyev (1834-1907) a Russian chemist is first to devise a periodic table of elements.…
