when metals combine with nonmetals the metallic atoms tend to

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..

Hydrogen combines with non-metals, to give the respective hydrides. With oxygen Hydrogen burns in oxygen to form water. Instead of igniting the mixture, if a small quantity of well divided platinum is added to the mixture of the two gases, they instantly combine t..

We are familiar with the fact that the atoms of all elements, except noble gases, have an incomplete outermost shell. Consequently, most elements are reactive and they try to achieve the stability of the noble or inert gases by electron transfer or by electron sharing. After this co..

Both lithium and sodium combine directly with hydrogen, sulphur, halogens and other non-metals on heatin..

Magnesium combines with non-metals on heating. ..

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 Caesium melt below 30 . So..

With hydrogen - When hydrogen is passed through boiling sulphur, both hydrogen and sulphur combine to form hydrogen sulphide (Fig.13.28..

Let us look at the way acids react with metals. a) All metals above hydrogen in the metal reactivity series generally react with dilute acids to form their respective salt and liberate hydrogen. Metal + Acid Salt + Hydrogen b) Very active me..

fig 1.22 - Overlapping of s and p bands in group II elements Metals are extreme examples of delocalized electrons. In a metallic crystal the electrons are free to move throughout the crystal. However, the metal ions are fixed in position and can only vibrate. When a ..

. They do not turn blue litmus to red but treated with active metals liberate hydrogen. The acidic character of alcohols is due to the presence of polar O-H group. Due to greater electro negativity of oxygen atom, the shared pair between O and H is drawn towards the oxygen ..
