Calcium is a vital element in the human body and plays many important biological functions, especially in muscle contraction, nerve impulse transmission and bone mineralization. An understanding of calcium chemistry is vital to both recognizing and appreciating the importance of calcium in relation to biological...
What properties define gases?
By: D. Vogt
Gas is a basic state of matter, along with solids, liquids, and plasma. Gases have higher energy than solids or liquids, and are characterized by molecules that move freely, and by their capacity to expand to fill any container they are placed in. Many of...

What properties define liquids?
By: D. Vogt
Liquids are one of the four phases or states of matter, along with solids, gases, and plasma. Liquids will always flow in order to fit the shape of the container they are poured into. This makes them like a gas. However, like a solid, liquids...

The question of whether or not time travel should be allowed if it were possible is a good one. Time travel would have moral implications if it was possible and so there would be lots of debate on the subject if anyone actually proved it...
What is atomic weight?
By: D. Vogt
Atomic weight refers to the mass of an average atom of a particular element. This weight is calculated by adding together the number of protons and neutrons in the average nucleus (electrons, which also form an atom, are of extremely low mass and are therefore...
Explaining Rutherford's atomic theory
By: D. Vogt
Between 1909 and 1911, British chemist Ernest Rutherford developed a new theoretical model of the atom which overturned existing hypotheses and became the dominant means of understanding these basic building blocks of all matter for most of the twentieth century. Although several components of the...
