elements through tests and then being able to organize the metals‚ nonmetals‚ and semimetals on the periodic table. The purpose of this lab was achieved. As a class we were able to take the elements and then test them to find out their individual properties. We were then able to distinguish if the element was a metal or nonmetal based on the property’s we found. We then placed the elements on our own periodic table sorted by atomic order. One metal that I tested was magnesium. I observed that this element’s

chemical change. (5 points) Score 2. For each metal that participated in a chemical change‚ write the type of metal it is‚ based on your examination of the periodic table. Answer: Ammouniam Vandrate had a chemical change but it turned out to be a transition metal‚ no other metal. The sulfates had more transition atoms going through the chemical‚ more than an original transition atom normally. Doing this showed me also that iron nitrate is an transition metal as well‚ same with the cobalt‚ copper‚ and

This experiment will help one understand how a flame test is performed and that every metal has a unique bright line spectra. This means a bright line spectra can be used to identify any element. This information can be used to identify elements in space to tell whether a planet has oxygen on it or not. If one can tell if a planet has oxygen

of different kinds of metal. We used pennies made out of different metals to determine this. After we gather the data‚ it’ll be used to determine the metal used. Hypothesis: In the lab‚ I expect that the pennies before 1982 would be heavier than those that are after 1983 because the metal was initially changed because the earlier pennies cost more to make. So I think that since the heavier metal was more expensive to make‚ then they just used a cheaper metal. So if the metal was heavier it may have

Failure Due to Aging 2. The main causes for the structural failure of an aircraft due to aging are briefly discussed as following. (a) Metallic Corrosion. The deterioration of the surface of a metal due to a chemical reaction is called metallic corrosion. This occurs because metals come in contact with electrolyte mostly contaminated water. As it arises‚ it may go undetected and result in loss of integrity of metallic structures. Since metallic corrosion is directly related to structural

this element I thought it was some type of gas but it can turn it to a liquid at a certain type of liquid. But is actually a very shiny type of metal. Rubidium was discovered by Kirchoff and Bunsen in 1861 through the use of a spectroscope. Rubidium metal can be made by minimizing rubidium chloride with calcium with other substances. The cost of this metal in small quantities is approximately 25 U.S. dollars a gram. This element is obtained in the earths crust which is very useful to people. It is

Lure of precious metals: Precious metals were a major pull factor for the west because everybody was looking for the opportunity to become wealthy individuals which was known as the American dream at that time. Gold and silver was the metals that every single person was looking for in the westward expansion‚ immigrants and citizens were willing to kill to get their hands on any gold or silver mine. The killing‚ weirdly enough‚ was mostly was the removal of Indians. The India wars: War was inedible
