All materials on earth are made up of one or more elements. Elements are substances that have atoms of only one kind. Any one element may have some of the same properties that other elements have, but no two elements are exactly alike. For example, hydrogen and helium are both colorless, odorless, and tasteless gases. They are both lights, but helium is heavier. Hydrogen burns, but helium will not.
All elements have a certain weight. They can be a solid, a liquid, or a gas. Some will dissolve in water. Others must be heated to a certain tempemture before they will change from a solid to a liquid or to a gas. These characteristics are called “the physical properties” of elements.
After scientists studied the physical and chemical properties of elements, they grouped the elements that were alike together. These elements are called “chemical families”.
All the families were combined into “the periodic table of elements”. They were listed in order of their “atomic number”. The atomic number of an element depends on how many protons, particles with a positive charge, each element contains. A hydrogen atom has one proton and its atomic number is one, so it is axt on the periodic table.
Some elements are named after people or places or countries: Einsteinium, Europium, Gernianium, Califomium, and Scandium. Among the familiar elements are carbon, copper, gold, iron, lead, mercury, nickel, platinum, tin, radium, and silver.
What Are The 5 Elements Of Nature?
Everything in nature is made up of five basic elements: earth, water, fire, air, and space. Knowledge of the five elements allows the yogi to understand the laws of nature and to use yoga to attain greater health, power, knowledge, wisdom, and happiness.
