Elements and Compounds. What is the first statement of the video?
Elements And Compounds: everything around us whether it is gas-liquid or solid is made up of matter.
When matter is observed closely it is seen to be made up of tiny particles called atoms.
Atoms combine to form molecules that make up different kinds of substances around us.
The molecules that make up matter can be classified as elements or compounds let us learn more about these today
Let us use some colored beads to understand how elements are different from compounds

Elements and Compounds. What is the Sixth statement of the video?
Consider the yellow beads as oxygen atoms, the red beads as hydrogen atoms, and the blue beads as carbon atoms
Let us try to make an oxygen molecule, a water molecule, a carbon molecule and a carbon dioxide molecule, using these atoms
You know that one oxygen molecule is made up of two oxygen atoms.
So here we go one and two oxygen atoms put together and we have an oxygen molecule.
Now the water molecule, one water molecule is made up of two hydrogen atoms. and one oxygen atom, so we need one yellow bead and two red beads to make one water molecule.

Elements and Compounds. What is the Seventh statement of the video?
This seems interesting let us continue to make the carbon molecule and the carbon dioxide molecule
Let us try to make an oxygen molecule, a water molecule, a carbon molecule and a carbon dioxide molecule, using these atoms
You know that one oxygen molecule is made up of two oxygen atoms.
So here we go one and two oxygen atoms put together and we have an oxygen molecule.
Now the water molecule, one water molecule is made up of two hydrogen atoms. and one oxygen atom, so we need one yellow bead and two red beads to make one water molecule.
