Chemistry assignment Introduction: Throughout modern day society metals are constantly used‚ in fact mankind has been heavily dependent on metals for the last several hundred years. But the science behind metals has only been discovered in recent years and has now become known to people that we simply could not live without them. Metals make up around 80% of the elements (currently discovered). They are used in everyday items that society depends on‚ such as: cars‚ re-bars for building‚ window

IGCSE Complete Chemistry Notes Unit 1: States of matter Everything is made of particles. Particles in solid are not free to move around. Liquids and gases can. As particles move they collide with each other and bounce off in all directions. This is called random motion. In 2 substances‚ when mixed‚ particles bounce off in all directions when they collide. This mixing process is called diffusion. It’s also the movement of particles without a force. The smallest particle

Ruthenium is the 44th element on the periodic table of the elements. Ruthenium was named after the Latin name for Russia‚ Ruthenia. It is a very rare‚ silvery‚ and shiny transition metal found in South America‚ North America‚ and South Africa. Ruthenium was found in 1844 by Karl Karlovich Klaus. In 1808‚ a Polish chemist named Jedrzej Sniadecki found an element he called vestium in platinum ores from South America. When French chemists tried to repeat his work‚ however‚ they did not find it in the

transfer heat away from the computer’s processor. Heat sinks are usually made of metal‚ which serves as the thermal conductor that carries heat away from the CPU. However‚ there are pros and cons to using every type of metal. First‚ each metal has a different level of thermal conductivity. The higher the thermal conductivity of the metal‚ the more efficient it is at transferring heat. One of the most common metals used in heat sinks is aluminum. Aluminum has a thermal conductivity of 235 watts per

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 makes silver is an ideal metal for all kinds of industrial use. Silver occurs in lead‚ Zinc and copper ore deposits. Lead ore is the main source of Silver. In fact‚ 75% of the resources in the world are found in association with other metal ores. The most important mineral is argentite‚ Sulphur Sulphide
