Carbon dioxide is made of molecules of a carbon atom bonded to two oxygen atoms (CO₂). Atoms can be drawn as circles. But all the atoms of an element need to look exactly the same. When drawing ...

Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

When fast-moving atoms or molecules hit slower-moving atoms or molecules and increase their speed, heat is transferred. This process is called conduction. Draw motion lines in the 'After' picture to ...
