Question

What is made of two or different elements chemically combined?

Answer 1

Hint : The combination of two or more different elements formed by the chemical means can be broken down further by the chemical methods only. The physical methods are not applicable for them as the physical methods can only separate the mixtures.

Complete Step By Step Answer:
As we know many different elements like hydrogen, carbon, oxygen, chlorine, fluorine, sulphur, sodium etc.
So, these elements combine chemically to form the compounds.
Compounds are substances made up of a variety of elements that bond chemically.
These compounds are further breakable back into their elements but only by the various chemical methods according to the property of the compound.
As now we are talking about the properties of the compound, it is very important to note that the properties of the compounds are very much different from the properties of their individual elements.
So let’s understand this concept using the example of sodium chloride $(NaCl)$ . $(NaCl)$ Is made up of the elements sodium $(Na)$ and the chlorine $(Cl)$ .
Sodium is a soft metal but very reactive in nature and cannot be placed open in the contact of air
On the other hand chlorine is the poisonous yellow gas
But together chemically bonds in the compound $(NaCl)$ have different properties, as sodium chloride is one of the important parts of our food and can be placed outside in air and is not poisonous.

Note :
Compounds now are the inseparable part of the living beings as everything around us is composed of different elements and in turns are compounds like starting from the very essentials like water $({H_2}O)$ , salt, soaps, toothpastes, sucrose i.e. sugar.
