- under chemical property matter can be divided into pure substances and mixtures let us learn about pure substances first A substance, which is made up of only one kind of particles and is free from any kind of mixture with constant structure is termed a pure substance. we can further categorize pure substances into elements and compounds . under elements we have metals, metaloids,and non-metals . under compounds we have organic compounds and inorganic compounds .
- lets understand what are compounds . compound is a chemical substance formed by a union of parts or elements .organic compounds are chemical compounds containing carbon hydrogen bonds. whereas inorganic compounds are any substance with 2 or more chemical elements that lack carbon hydrogen bonds . elements on the other hand can be defined as a substance which cannot be spilt up into two or simpler substances by the means of chemical methods of applying heat, light or electric energy.
- sir can you explain what are mixtures and the types of mixtures ?
-  A mixture is made when two or more substances are combined, but they are not combined chemically. there are two kinds of mixtures homogenous and heterogenous mixtures .A homogeneous mixture is a gaseous, liquid or solid mixture that has the same proportions of its components throughout a given sample. A A heterogeneous mixture is a mixture with a non-uniform composition. The composition varies from one region to another with at least two phases that remain separate from each other, with clearly identifiable properties. i hope children u have understood all of this ?
- yes sir...we have completely understood the properties of particles in matter .thank you sir .
