Which magnesium experiment !
Magnesium is a highly reactive metal compared to gold, silver and copper. It will form a magnesium oxide as an outer-shell when it comes to contact with oxygen in the air, and it reacts with water, creating hydrogen gas and fizzing.
Metal reacting with oxygen is known as oxidation. A common form of this process is found in the rusting of iron, where the iron reacts with oxygen to form iron oxide (known as rust).
Any metal that reacts with oxygen will produce a metal oxide. For example, magnesium reacts with oxygen to produce magnesium oxide, and zinc reacts with oxygen to produce zinc oxide. It is helpful to know the general word equation: metal + oxygen -> metal oxide
Magnesium is the element that loses 2 atoms when reacting, reacts slowly with water, and can conduct electricity.
Gold reacts with few elements including chlorine, oxygen and fluorine under critical conditions.
Beryllium is the only alkaline metal that reacts to oxygen but not to water. The hydrogen in water stabilizes the reaction.
Yes; the final compound is the oxide Au2O3; this compound has some useful applications.
Magnesium chloride is an ionic compound. It is formed when magnesium (a metal) reacts with chlorine. The resulting compound contains positively charged magnesium ions and negatively charged chloride ions held together by strong ionic bonds.
No.
Magnesium readily reacts with CO2 because it is a more reactive metal that can displace carbon from carbon dioxide through a redox reaction. Gold, on the other hand, is a noble metal that is very unreactive and does not readily undergo chemical reactions with CO2.
Gold does not react with air or water, so it does not tarnish or corrode easily. Copper reacts slowly with air and water to form a patina. Silver reacts with sulfur compounds in the air to form tarnish. Iron reacts quickly with oxygen to form iron oxide (rust).
Metals in the reactivity series from aluminium to copper react with oxygen in the air to form the metal oxide. Aluminium and Zinc reacts very quickly, Iron reacts slowly at room temperature. Tin, Lead and Copper reacts with Oxygen in air when heated. Silver, Gold and Platinum do not react with Oxygen in air
