Introduction to Basic Chemistry_3

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 Second statement of the video?

• Consider the yellow beads as oxygen atoms, the red beads as hydrogen atoms, and the blue beads as carbon atoms

• 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 Third 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

• 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 Fourth 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.

• 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 Fifth 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.

• 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.

Elements and Compounds. What is the Eighth statement of the video?

• This seems interesting let us continue to make the carbon molecule and the carbon dioxide molecule

• One carbon molecule is made up of two carbon atoms, so here is one and two put together and we have a carbon molecule

• 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 Ninth statement of the video?

• This seems interesting let us continue to make the carbon molecule and the carbon dioxide molecule

• One carbon molecule is made up of two carbon atoms, so here is one and two put together and we have a carbon molecule

• The carbon dioxide molecule on the other hand is made up of one carbon and two oxygen atoms. So here is one molecule of carbon dioxide

• 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 Tenth statement of the video?

• This seems interesting let us continue to make the carbon molecule and the carbon dioxide molecule

• One carbon molecule is made up of two carbon atoms, so here is one and two put together and we have a carbon molecule

• The carbon dioxide molecule on the other hand is made up of one carbon and two oxygen atoms. So here is one molecule of carbon dioxide

• Here are all molecules we have made so far. Do you notice that the molecules of oxygen and carbon are made up of only one kind of atoms?

• 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.
