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