and Mixtures

Learning Outcomes Key Concepts
Students will be able to
• Elements
• defi ne elements as substances made up of iden cal atoms.
• classify elements as metals and non-metals based on their proper es. • Symbols of Elements
• Compounds
• defi ne compound and mixture, and discuss the diff erences between the
two. • Atoms and Molecules
• use symbols of elements and molecular formulae of the compounds to • Uses of Some Elements
represent their names as short hand nota ons. and Compounds
• separate diff erent components of samples of some mixtures. • Mixtures
• discuss the reasons for selec ng a specifi c technique for separa ng the • Separation of Mixtures
components of a mixture.

In previous classes, we have learnt about ma er and its states. We have also learnt that various states of
ma er are the result of diff erent arrangements of their molecules. In this chapter, we will study about the
composi on of ma er in detail.

We can classify ma er on the basis of some similari es and dissimilari es in their composi on.

Examples:
• Water and oil are both liquids but they diff er from each other because their composi on is diff erent.

• Salt and sugar are solids but they are made up of diff erent kinds of ma er and hence they diff er
from each other.
