Lab experiments show how magnesium, zinc, iron, and copper react with hydrochloric and nitric acids. Also shows the displacement of two metals from salts.
It is important to properly dispose of metals for the safety of people and the environment. Due to potential contamination problems, environmental programs focus on the recycling, reusing, and reducing of metals.
Every portable electronic device is fueled by chemistry, specifically through oxidation-reduction or redox reactions. In redox reactions, one compound gains electrons (reduction) and one compound loses them (oxidation). Chemists can set up reactions so that electrons are forced to move in a certain way to create an electrical current. Metals often play a key role in redox reactions, which are essential to all aspects of chemistry, particularly in many biochemical processes. Part of the series Chemistry: Challenges And Solutions.
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element".
Caesium has the atomic number 55 and symbols Cs. It is an alkali metal with a silvery-gold color and the only liquid metal from the group of elemental metals, which is liquid near or at room temperature.
Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal.
Science lab experiments demonstrate what happens visibly and at a molecular level with the Group 1 highly reactive metals and the Group 17 highly reactive halogens from the periodic table. Experiments also illustrate the range of reactivity among metals. Video has three 5-minute segments for convenience.

Indium is a chemical element with the symbol In and atomic number 49. Indium is the softest metal that is not an alkali metal.
Rubidium is the chemical element with the symbol Rb and atomic number 37. Rubidium is a very soft, silvery-white metal in the alkali metal group.
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal.
Niobium, also known as columbium, is a chemical element with the symbol Nb (formerly Cb) and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal.
Silver is a chemical element with the symbol Ag and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.
Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal.Under standard conditions, it is the lightest metal and the lightest solid element.
Tests the heat zones of a Bunsen burner and shows some elements' coloration when placed in the flame. Notes that chemistry is everywhere, in both natural and man-made components.
Strontium is the chemical element with the symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly chemically reactive.
