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.
This is not exactly accurate; while atoms are matterâthe smallest pieces of matter you can findâmolecules are the smallest bits of compounds. And particles arenât matter, but the building blocks of it. For example, copper is an element. A copper atom is the smallest piece of copper that exists. Hydrogen is also an element; two hydrogen atoms and one oxygen atom combine to form a molecule of water, which is a compound. While atoms are the tiniest bits of matter, they are made of the sub-atomic building blocks of matterâprotons and electronsârevolving around a nucleus.
