Fluorine (F) is the most chemically reactive element and most electronegative element of all the elements. Fluorine is a Group 17 element, situated at period 2 and the 9th element in the Periodic Table. Even with its extreme reactivity, fluorine has many useful applications. In...
Element facts: Calcium
By: Retha Boswell
Calcium (Ca) is a non-toxic alkaline earth metal. Alkaline earth metals are in the second group on the periodic table, with calcium being in period 4, atomic number 20. All of the elements in the group are very reactive and none are found free in...

Flourine (F) has a special place in science because it is the most reactive of all the elements, and participates in almost all inorganic and organic chemical reactions. The reactions exclude oxygen, neon, krypton and helium. Its name has originated from the French word &ldquo...
Element facts: Calcium
By: Steven Mars
The element calcium has atomic number 20 in the Periodic Table of Elements, which means it has 20 protons in its nucleus. It is group IIA. Its symbol is Ca and its atomic weight is 40.078. It is an alkaline earth metal. It was...

On earth there are many things humans have spent decades or even centuries trying to figure out. The world is full of amazing things. Science and chemistry can often help explain many things that seem too remarkable to be true or too complex for some...
Chemistry: Why air is colorless
By: Shaheen Daad
In response to the question of why air is colorless, the chemist provides a very simple answer. It is only because the gases that make up air are all colorless. There might be some trace gases like chlorine and nitrogen dioxide, which are colored yellowish...
