Joseph Priestley was a famous chemist. He was famous for inventing soda water, his writings about electricity, and his discovery of gases. Joseph was born on March 24, 1733, in Bristall. He died February 6, 1804 at the age of 70. Joseph is most known for his discovery of oxygen and for isolating it. Oxygen was not first discovered by Joseph, instead the famous Swedish chemist, Carl W. Scheele, in 1772. Joseph discovered Oxygen independently in 1774. Joseph published his findings in the…

The element name given is Phosphorus, it is symbolized in on the periodic table as a P. Its atomic number is 15 and the atomic mass is 30.974 (which is a rounded number). Group number the element is apart of on the periodic table is 15. Phosphorus’ listed isotopes are P-31 (stable) and 23 others and its electron configuration is [Ne]3s2 3p2. Physical properties of the element are varied depending on which allotrope of the element you are talking about. White Phosphorus has a melting point of…

What are group one elements? Group one elements are alkali metals. The physical properties of group one elements are that they are shiny and the alkali metals are very soft. Lithium is the hardest alkali metal and they become softer as you go down the group. The chemical properties of group one is that they’re very reactive when mixed with water or when in contact with the air. Each element in group one has one electron in their outermost shell. Also, group one elements get more reactive as you…

Kevlor A synthetic material which has high tensile strength and used in manufacturing of tires and also as a reinforcement agent in manufacturing of protective parts like helmet etc…, HISTORY In 1930’s a chemical company called DuPont prepared commercially succeful super polyamide. Actually in 1964 Stephanie kwolek discovered kevlor in DuPont laboratory while doing research on the high performance chemical compounds. Kevlor is patented Stephanie kwolek in 1966 which is used by many police…

Neon is a nonmetal, colorless gas that has an atomic weight of about 20.180. This element was discovered by Sir William Ramsay in 1898 and contributions also came from Morris Travers. I will go into greater detail about how they discovered neon later into the essay. Neon’s atomic number on the periodic table is 10. It is also odorless, colorless, and non-toxic. As I stated earlier, neon was discovered at the University College London by Sir William Ramsay and Morris Travers in 1898…

Phosphorus (chemical symbol P) is an element that comes in the form of three allotropic. A white waxy solid, a red powder or black powder .White phosphorus is poisonous and when it comes in contacts with air (0) it can spontaneously ignite, which is why white phosphorus is stored in water (figure A). Phosphorus boiling point is 280°C and a melting of 44°C. When phosphorus is boiled it forms a red powder (figure B) which is found in the head safety matches (figure C). Black phosphorus is created…

It is an element. It is rare. It is Hassium. Out of a total of 118 elements on the Periodic Table of Elements, Hassium is just one. Hassium is the 108th element on the periodic table. Have you ever heard of Hassium? The term Hassium was derived from a german state of Hesse, where Hassium was first made. Hassium was discovered in 1984 by Peter Armbruster and Gottfried Munzenburg. These two inventors developed this element in Darmstadt, Germany which is located in Europe. Hassium has a…

Atomic vitality happens Eventually Tom 's perusing splitting Also combination. Atomic splitting may be Possibly a atomic response or An radioactive rot transform done which the core of an molecule parts under more diminutive parts (light nuclei). Those splitting procedure often produces nothing neutrons Also photons (in those structure about gamma rays) Furthermore discharges a huge add up from claiming vitality. Atomic combination will be a atomic response for which two or All the…

Theq element on the Periodic table that is best representation of my personality would be element 13, Aluminum. Properties of Aluminum its included high melting point, conductivity, malleability, and non-toxicity. Aluminum’s high melting point represents my determined personality. This is because I can face adversity well. Even when situations occur that are extremely unfavorable I am able to keep a cool head and think straight. I can persevere and stay strong allowing myself to solve and get…
