What are two physical properties of magnesium metal?
Physical Properties: Magnesium is a shiny, silver or gray colored metal that is light in weight and strong. Th density of magnesium is 1.738 g/mL, which means the metal will sink in water, but it is still relatively light weight.
What are the physical and chemical properties of elements?
We learned that physical properties are things like shininess, conduction of heat or electricity, melting point, and density. Chemical properties include things like reactivity to oxygen, flammability, and ability to hold on to electrons during a chemical reaction.
Is flammability a chemical property of magnesium?
Magnesium metal and alloys are highly flammable in their pure form when molten, as a powder, or in ribbon form. Burning or molten magnesium metal reacts violently with water. Magnesium powder is an explosive hazard.
What are the chemical properties of magnesium hydroxide?
Magnesium hydroxide has the chemical formula Mg(OH)2 and the molecular weight of 58.3197 g/mol. Its CAS number is 1309-42-8 and its density is 2.345 g/cm3. It decomposes when heated to 360 °C and forms the oxide, MgO. It is very slightly soluble in water at 0.00122 g/100 ml and has a solubility product of 5.61 × 10−12.
What is the physical state of magnesium?

What are 5 chemical properties hydrogen?
At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
Is magnesium Reactive or nonreactive?
Halogens: When reacted with a halogen, magnesium is very reactive. An example will be with chloride. When reacted with chloride, the product is magnesium(II) chloride. Acids: When reacted with acids, magnesium dissolves and forms solutions that have both the Mg(II) ion and hydrogen gas.
