CHEMICAL PROPERTIES-OF METALS-.

1.	CHEMICAL PROPERTIES-OF METALS-.
Answer» Ans :- The density of metals is usually high. Metalsare malleable and ductile. Metals form an alloy with other metals or non – metals. Some metals react with air andcorrode. For e.g. Iron. Metals are good conductors of heat and electricity.Leadis an exception. Generally, metals are in a solid state at room temperature. Except for Mercury. Mercury is in a liquid state. Many metals produce metal oxide by burning in the oxygen of the air.Highly reactive metalsreact violently when they’re burnt in oxygen. Metals like sodium and potassium are stored in oil as they react with air in seconds. They’re highly reactive metals. Less reactive metals like gold, silver, platinum, etc do not tarnish easily. They stay shiny and lustrous. Metals produce metal oxide andhydrogengas while reacting with water. Soluble metal oxides dissolve in water and create metal hydroxide.
