Scientists didn't discover the noble gas helium - the second most common element in the universe - on Earth until 1895. And they thought it existed in minute quantities only, until miners found a huge underground cache in Kansas in 1903.

Natural gas is hemispheric. I like to call it hemispheric in nature because it is a product that we can find in our neighborhoods.

Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality of the atoms of different elements consist.

Noble bold is an accident of fortune; noble actions characterize the great.

The pure air and dazzling snow belong to things beyond the reach of all personal feeling, almost beyond the reach of life. Yet such things are a part of our life, neither the least noble nor the most terrible.

In a gas, motion has the upper hand; the atoms are moving so fast that they have no time to enter into any sort of combination with each other: occasionally, atom must meet atom and, so to speak, each hold out vain hands to the other, but the pace is too great and, in a moment, they are far away from each other again.

Despite its obscurity, probably no element on the periodic table has as colorful a history as antimony. Money, madness, poison, linguistics, charlatanism, sex - pretty much every theme that runs through the periodic table can be found in Element 51.

Even when they are saturated in the sense of the older theory of valence, the elementary atoms still possess sufficient chemical affinity to bind other seemingly also saturated atoms and groups of atoms, under generation of clearly defined atomic bonds.

There is a noble and a base side to every history.
