Meta element

the elements on the periodic table. The Disappearing Spoon focusses on the history of the Periodic Table by telling stories that show how each element affected the scientists that discovered it. For each element, Kean supplies an extensive backstory for its foundation, the common (or uncommon) uses of the element and other useful factoids about the matter. The author begins the novel with a physical description of the Periodic Table as a whole; he discusses the names of the groups of elements…

other reactants. 3.What is the name of the gas that was collected in Reaction #3? Back up your answer based on what you know about the identity of that gas and its well-known chemical properties. The gas we got was hydrogen. Hydrogen is a chemical element with the atomic number 1, and has the chemical symbol of H. It is known to be very flammable, and it is also used as a fuel source for a space shuttle’s main engine. So when the fire lit inside the tube, the hydrogen reacted and created a…

For many years helium was known as an element that might exist on the sun but unknown on the Earth. Sir William Ramsay discovered helium after treating a uranium mineral. Lockyer and Professor Edward Frankland suggested the name helium. A sample of the gas was sent to Sir William Crookes and Sir Norman Lockyer who identified helium.The name is derived from the Greek 'helios' meaning sun, as it was in the sun's corona. Helium is a gaseous chemical element,with a symbol of He. Its atomic number…

substances has the properties it does is a subject called chemistry.” Chemistry involves many things, from atoms to elements and their functions. It is a wide field of science with an extensive early and modern history. It also involves chemical reactions, and what they are. Chemistry consists of many complex processes and objects. Some of the most important parts of chemistry are atoms, elements, and properties. Atoms are the particles that make up everything, from a chair…

and Overview Elements are the substances that make up everything in the universe, known and unknown. This means that elements are what make up matter, and everything you see, hear and touch. There are 118 elements known to man, some that you may know include gold, iron and oxygen. Each of these have distinguishing qualities and they come in 3 different states of matter, solid, liquid and gas. Some of these are man-made but most have been discovered. The things that make each element have a…

The element that I choose for this project is called Strontium. Strontium is a chemical element with the symbol (Sr) and it has atomic number of 38. It is an alkaline earth metal, and is a soft white yellowish metallic element which has highly reactivity chemically. It’s properties are mostly intermediate between aand similar to those of its group neighbors calcium and barium. When it is exposed to air, the metal forms a dark oxide layer. Strontium has 38 protons, 50 neutrons, and 38 electrons.…

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 same year that he discovered the element. Three years later Scheele published his findings on the element. There is a lot of debating in the world of science on who discovered Oxygen first. Most of the credit is given to Priestley or both him and…

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…

used in many industries including mining and iron and steel production. Additionally, cyanide treats wastewater. According to Wu, F. et al. (2014), socio economics status would be a factor likely to increase exposure of foodborne toxicity because people with low-income consume only one or two foods. On the other hand, children under 18 years old are at high risk in toxicological effects of cyanide since they are immature and differ from adult (ATSDR, 2006). Cyanide compounds would be lethal…

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…
