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.
Elements are the simpliest form of complete matter, for example a single hydrogen (H) atom. When atoms combine and share electrons, they form compounds or molecules, such as H2O, water.When many very complex compounds combine in a very unique manner within a cell, they form the necessary parts of that cell organs or organelles. molecule is a combination of atoms into a single substance. A compound is a molecule that includes atoms of two different elements. Organelles are parts of cells made up of many, many atoms, such as the mitochondria.
