Differences between metals and non metals


          Metals and non metals

 Elements-Asubstancethat can not broken down into simpler substances in chemical reaction.




Elements can be classified  in two parts based on their properties.

1.metals
2.non metals




Metals

On the periodic table,   By a zig-zag line metals are separated from nonmetals    stepping through carbon, phosphorus, selenium, iodine, and radon. Nonmetal is a part of element that is right to the metal.Element just to the left of the line may be termed metalloids or semimetals and have properties intermediate between those of the metals and nonmetals. 

      According to periodic table there are various kinds of metals.

1. Alkaline metals
2.Alkalineearth metals
3. Transition metals
4. Lanthanides
5.Actinides

Non metals


The non metals are those that do not look like metals and it's properties are different from metals. According to the periodic table ,In periodic table non metals are very less as compared to metals and it's position is on the right side of the periodic table.
Example
1.hydrogen
2.nitrogen
3.carbon
4. oxygen
5.sulphur



Chemical Properties

Metals


*Metals corrode easily and fast.

*Usually,  In their outer most  shell have 1-3 electrons.

*Easily they can Lose their valence electrons.

*They form basic oxides in nature.

*Are good reducing agents.

*Have lower electronegativities.

Non metals


*Usually ,In their outer shell have 4-8 electrons.

*Easily they can Gain or share valence electrons .

*It usually Form  acidic oxides in nature.

*Are good oxidizing agents.

*Have higher electronegativities.

Physical properties

Metals


*It has high density.

 *Metal is a good conductor of heat and electricity.

*It is a Malleable  can be beaten into thin sheets.

*It is a Ductile can be stretched into wire.

*Possess metallic luster.

*Opaque as thin sheet.

*It is Solid at room temperature (except Hg).

Non metals


*It is Poor conductors of heat and electricity.

*Brittle - if a solid.

*It is Nonductile.

*Do not have metallic luster.

*Transparent as a thin sheet.

*Solids, liquids or gases at room temperature.

         chemical and physical changes. Areyou confused about chemical change and physical change.let's study about chemical change and physical change .              Chemical  vs physical 1.Define chemical and physical 2.comparision chart 3.key points 4.conclusion Q.1 what do you mean by chemical changes and physical changes.explanation with suitable example? Chemical changes             A chemical changes is a type of changes it is a form of matter   new substance are formed after under goes chemical reaction and having it's identity .It can not reverse some time later is known as chemical changes. Example  of chemical changes 1.Burning of wood 2.Digesting food 3.Reaction with acid and base 4.souring of milk 5.Rusting of Iron 6. Burning of candle Physical changes              A physical changes is a type of change  which is a form of matter ,No new substances are formed and substances is not transformed into anoth

Differences between soap and detergent

                 soap and detergent Soap and detergent , Those  substances that dissolve in water and have ability or tendency to remove dirt from dirty surface  such as the textiles ,skin of humans and other solids and many other substances. 1.What do you mean by soap?    Soap is a long chain of carboxylic acid of sodium salt (Na)or potassium salt(k).  surfactants are used  (Between a liquid and another substance compounds that reduce the surface tension) and therefore help in the emulsification of oils in water.  Through the saponification of fats and oils soaps are generally formed.   The hydrocarbon tail is hydrophobic and other the carboxylate end of the soap molecule is hydrophilic 2.what is detergent ? Detergents are made from synthetic sources. Detergents are the potassium or sodium salts of a long alkyl chain ending with a sulfonate group.  Generally they are soluble in hard water. The sulfonate group does not attach itself to the ions present in
