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.
Most of the substances around us consist of molecules and are called compounds of various elements. Molecules are the smallest particle of a compound that has all the chemical properties of that compound. They are made up of two or more atoms, either of the same element or of two or more different elements.olecules and compounds contain their constituent elements in specific proportions that are characteristic of the compound. For example, water (H 2 O), a well known and simple compound, contains hydrogen and oxygen at a ratio of 2 to 1.
