Reactions of sodium and Potassium with Water A chemical demonstration of the reaction between sodium and water and between potassium and water. Carleton University, Ottawa, Canada.

Chemistry: The Periodic Table and Periodicity clip Animation succinctly develops the relationship between the electronic structure of an atom and its properties, demonstrating clearly why there are families of elements and gradual changes in the properties of elements arranged by atomic number across the table. 23 minutes, color.

The element song The location of the elements in the periodic table. Lyrics: There's antimony, arsenic, aluminum, selenium, And hydrogen and oxygen and nitrogen and rhenium, And nickel, neodymium, neptunium, germanium, And iron, americium, ruthenium, uranium, Europium, zirconium, lutetium, vanadium, And lanthanum and osmium and astatine and radium, And gold and protactinium and indium and gallium, (gasp) And iodine and thorium and thulium and thallium. There's yttrium, ytterbium, actinium, rubidium, And boron, gadolinium, niobium, iridium, And strontium and silicon and silver and samarium, And bismuth, bromine, lithium, beryllium, and barium. There's holmium and helium and hafnium and erbium, And phosphorus and francium and fluorine and terbium, And manganese and mercury, molybdenum, magnesium, Dysprosium and scandium and cerium and cesium.

This General Chemistry lecture is about radioactive decay kinetics, nuclear binding energy that can be released in nuclear fission and nuclear fusion reactions, carbon dating, and three medical applications of nuclear chemistry

The difference between nuclear vs chemical reactions -Brief explanation off radiation

in this General Chemistry lecture we discuss the structure and stability of nuclei, and the various ways that unstable nuclei undergo radioactive decay

is a polymer with the formula [-CH2-CH(COONa)-]n widely used in consumer products. It has the ability to absorb as much as 200 to 300 times its mass in water. Acrylate polymers generally are considered to possess an anionic charge. While sodium neutralized polyacrylates are the most common form used in industry, there are also other salts available including potassium, lithium and ammonium

NurdRage Presents: 4 ways to make fire without matches or lighters using chemistry. Warning: These experiments are for educational purposes only and are not meant to be repeated. First, a small mount of potassium permanganate is mixed with glycerin. The reaction might be too slow to do anything so we added a few drops of water to get things going. Second, a mixture of ammonium nitrate and zinc is place ontop of a paper towel. The finer the ingredients are the better this will work. To activate it a few drops of hydrochloric acid are added. (We are well aware that addition of chloride from salt or ammonium chloride will produce a water-activated mixture. But we specifically choose not to demonstrate this for safety reasons, as that particular composition can spontaneously ignite during handling causi
