We experimented on various elements: Mossy Zinc, Aluminum Turnings, Copper Turnings, Activated Carbon, and Iron Fillings. We identified the physical properties based on Color, Luster, Form, and Conductivity and the chemical properties based on reaction to HCl and CuCl2. We were tasked to identify if the given elements were metals or nonmetals. The result of our observation is shown in the image. Based on this, what elements are metals and nonmetals? Iron is known to be a metal however, the iron fillings did not conduct electricity and do not have a metallic luster. Does that mean they are not metal? Is it right to say "corroded" in the CuCl2, when the sample formed rust-like material on its surface?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
