The Commonwealth of Nations, formally known as the Commonwealth and previously referred to as the British Commonwealth, is a unique international organization which encompasses countries from across the globe. Many of these nations have historical ties to the British Empire, though the association is not based on political connections. Characteristics . . . Read more
A volcano is basically a natural opening in the crust of the earth where magma (lava), steam (along with other gases) and ash can escape. A volcano is like a chimney which transfers the molten rock, found in the depths of the earth, to the surface. Most volcanoes are dormant . . . Read more
Scandium is a silvery-white metal and is a chemical element with the atomic number 21 and is represented by the chemical symbol Sc. It is often classified as a rare earth element because it is mostly found with other rare earth elements. Despite this classification it isn’t all that rare . . . Read more
Canada is a large country located in the northern region of the North American continent. It is well known for areas of spectacular natural beauty and many of these regions have been protected as National Parks. These parks are administered by Parks Canada and the goal of this organization is . . . Read more
Calcium is a soft gray metal best known for being an essential element for living organisms, including humans. It is also a chemical element and is represented by the symbol Ca and the atomic number 20. Calcium is the fifth most common element on the planet by mass and it . . . Read more
Potassium is a highly reactive metal that is silvery-gray in appearance. It is a chemical element with the atomic number 19 and is represented by the chemical symbol K. It was discovered and first isolated by Humphry Davy in 1807. Potassium is formed by the nucleosynthesis of lighter atoms, which . . . Read more
Chlorine is a yellowy-green gas at room temperature with a very distinctive odor (commonly associated with household cleaning products that contain bleach). It is also a chemical element with the atomic number 17 and is represented by the chemical symbol Cl. There are over 2000 organic compounds that contain chloride . . . Read more

Phosphorus is a nonmetal that exists in a variety of different forms (allotropes). The most common forms are white and red phosphorus. These different forms of this element all have very different properties. Phosphorus is highly reactive, which means that it is never found in its elemental form in nature. However, it is very common in a number of different minerals and makes up about 0.1% of all rocks. Phosphorus is a chemical element with the atomic number 15 and the chemical symbol P. All naturally occurring phosphorus on Earth is made up of a single stable isotope. However, many other isotopes of phosphorus have been identified.
Silicon is a chemical element with the atomic number 14 and represented by the chemical symbol Si. It is a nonmetal element and is similar to the elements carbon and boron. Silicon is extremely common on Earth (it is the 2nd most common in the crust of the Earth) and in the universe (6th most common element by mass). It is very rarely found in free form and is usually found as a part of minerals with other elements. All naturally occurring is made up of one of three stable isotopes. However, a number of other isotopes of silicon have also been found. Let’s find out how many have been identified.
