Reaction of metals with oxygen : Metals react with oxygen under different conditions to form basic oxides. These basic oxides react with water to form bases which turn red litmus into blue. Sodium and potassium react with oxygen vigorously at room temperature. Magnesium reacted with oxygen only if ignited. It gives a bright dazzling flame and forms a white powder of magnesium oxide. Non-metals react with oxygen to form acidic or neutral oxides. Reaction of metal with water: Metal react with water to form oxides or hydroxides along with hydrogen.
Click here for Elements can be divided into metals and nonmetals and it is important to know whether a particular element is a metal or nonmetal. Metals like copper and aluminium are good conductors of heat and electricity, while nonmetals such as phosphorus and sulfur are insulators. What properties did you think of while categorising elements as metals or non-metals? Properties are the things that are special or unique about an object or a material. Question 3. Question 1: When you strike a metal with hard substance, a ringing sound is produced.

Iron does not occur in the native state as it is oxidized easily. Iron in elemental state occurs in meteorites. Iron is an important of haemoglobin of blood. Iron is also present plant and animal tissues.
Some elements show properties of both metals and non metals. They are called metalloids. Most metals are found in the combined states as oxides, sulphides, carbonates, silicates etc. Metals Metals are solids except mercury. Metals are hard except sodium, potassium etc.
