power point of chemical properties of metals and non metals

A detailed comparison of properties of metals and non-metals is given in table. Property Metals Non-metals State of matter These are usually solid, except mercury, which is a liquid at room temperature. Gallium and Caesiu..

Summary - An electrolyte is a compound (salt, acid or base), which in solution or in a molten state conducts an electric current and is simultaneously decomposed by it Electrolytes are ionised into electrically charged ions, which carry the current Charged ions move towards the oppositely charged e..

With hydrogen When hydrogen is passed through boiling sulphur, both hydrogen and sulphur combine to form hydrogen sulphide. ..

Earth is an abundant source of material. Man has intensively studied the properties of these materials extensively and found new methods of using them. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for some purpo..

. These developments indicate a gradual change in the life style of mankind. Today metals are so vital to the modern man that it is unthinkable to live without them. They are essential for the construction of houses, transportation, communication, electricity, household articles, scientif..

Chemical Properties of Metals - Metals are Electropositive Elements Metals are very reactive. Metals tend to loose electrons easily and form positively charged ions; therefore metals are called electropositive elements. Sodium ..

With most of the metals the reaction of sulphur is highly exothermic. Sulphur combines with metals under varying conditions of temperature to form the respective sulphide..

With sodium Introduce a small piece of sodium metal into a jar of oxygen. It combines with oxygen to form sodium peroxide. Allow a piece of sodium to burn in a deflagrating spoon, and then introduce it into another jar of oxygen. It burns with a brilliant yellow flame to form..
