Walk as fast as you can in a circle around a section of the pool that's about 3 feet deep (the more people, the better the effect). Do about 20 laps, then change direction for 10 laps. The resulting rush of water against your body will feel much like the jets in a whirlpool.
These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number. Protons and neutrons contribute nearly all of an atomâs mass; the number of protons and neutrons is an elementâs mass number.
Atoms are the building blocks of all materials, no matter how simple or complicated the material is. An element is made up of only one type of atom. Compounds are made up of different types of atoms combined together. A lump of copper is made up of only copper atoms. Water particles are made up of hydrogen atoms and oxygen atoms combined together. Scientists call this type of particle a molecule.
