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...
In terms of cosmology, what is meant by inflation?
By: Retha Boswell
In cosmology, inflation is a theory expanding upon the standard Big Bang Theory. Inflationary Theory proposes that there was massive, exponential expansion very early in the creation of the universe. Inflation is involved a lot in understanding the first moments the universe existed and accounts...
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...
