Calcium: A Chemical Element On The Periodic Table
Calcium is a chemical element on the periodic table with the symbol Ca with atomic number 20. Calcium is a soft- gray alkaline earth metal, fifth- most- abundant element by mass in the Earth’s crust. This element comes in the metal section on the periodic table. Sir Humphry Davy discovered this element in 1808. This element was discovered through electrolysis of a mixture of lime and mercuric oxide. Calcium is useful to produce glass, batteries and steel. It can combine with other elements and these compounds are used for variety of purposes. Calcium has a melting point of 842˚C and has a boiling point of 1484˚C

The Chemy Called Al By Wendy Isdell
1287 Words | 6 PagesNew elements continue to be added to the periodic table as science knowledge increases. In January of 2016, a news article reported elements with atomic numbers 113, 115, 117 and 118 as approved by the International Union of Pure and Applied Chemistry. These elements completed the seventh row of the periodic table. Isdell shows the concept that chemistry continues to expand when Julie names an element in the Land of Science that did not previously exist, Wendelium with the atomic symbol Wd (Isdell, 442).

Unknown White Compound Lab Report
1367 Words | 6 PagesChemical compounds that are available to determine are CaCO3, CaCl2, Ca(NO3)2, mgCl2, MgSO4, KCl, HCl, HC2H3O2, KNO3, K2SO4, NaC2H3O2, Na2CO3, NaCl, Na2SO4, HNO3, H2SO4, HNO3, H2SO4, NH4Cl, (NH4)2SO4, K2CO3, 0.1 M AgNO3, 0.2 M BaCl, Mg(s), NaOH, and KOH. To start this experiment, start with the flame test by gathering a Bunsen burner and a Nichrome wire. Connect the Bunsen burner with a rubber tube to a laboratory gas. To prepare solutions for the flame test, weigh out 0.205 gram of Unknown Compound using an analytical balance and mixed it into a 140 mL beaker filled with 20 mL ionized water. Ensure that solid is completely dissolved using a stirring rod.
Chemistry 101 Chemistry
520 Words | 3 PagesMany people do not realize that chemistry is a part of our day to day lives. One specific thing we see on a daily basis is the colors and paint people use in paintings, on buildings, and any other place paint could be. When this paint is developed, the people who make it have to decide exactly what the compound should be made up of. This is an important thing to consider when making these paints because as discussed in Chemistry 101 lab, compounds are different things that develop one item, in this case it is paint. They have to make sure that the paint is homogenous because if it was heterogeneous when being applied, the paint would not go on well.
Plutonium: Legendary Period Table Of Elements
1310 Words | 6 PagesPlutonium, also known as Pu, is one of the many elements that are included on the legendary Period Table of Elements. It is the chemical element that holds the atomic number 94 and is a very dense, silvery, radioactive metal that can be found in the fuel in nuclear reactors as well as in explosives for nuclear fission weapons. But, recently Gregory R. Choppin Professor of Chemistry at Florida State University, Thomas Albrecht-Schmitt, has unlocked an amazing plutonium discovery providing evidence that plutonium (and other chemical elements) can offer so much more to our world! In fact, Thomas and his team have found that possibly, other than (or instead of) using Pu as a part of the world’s nuclear energy strategies, we can use it to help develop
Nacl Mixture And Freezing Point Lab Results
848 Words | 4 PagesBackground Information In this lab KCl, NaCl, and a mixture of MgCl2 and NaCl are the independent variables that all lower the freezing point of water. Ice is used as the controlled variable because it is what the salts are lowering the freezing point of. Salt (Na) weakens intermolecular forces of water, thus lowering the the freezing point. This is why in colder climates where icy roads and walkways are a liability, salt is often scattered over areas that are slick with frozen water.
Difference Between Bronze Age And Iron Age
1054 Words | 5 PagesBronze is made of copper and tin. While copper is plentiful tin is not. To complicate matters the two metals are rarely found near each other, which is why trade during the Bronze Age was so important. Ancient metallurgists were forced to look for another source of metal due to the Bronze Age Collapse, as they no longer had tin to make bronze. Iron was not a new discovery; the Hittites had used iron since 2000 BC.
