It does not seem, however, that organic chemists were much worried about barriers to rotation in organic molecules in general at that time because there was no technique available to demonstrate the phenomenon experimentally.

One day I discovered that one could get the barrier to internal rotation in ethane approximately right using this method. This was the beginning of my work on organic molecules.

When I define polarities in my work, I actually create the space between things. I point to the question I am actually interested in, without naming it.

I think there's a little bit of sizzling here. Honestly, I can feel it. The ions are flying back and forth.

The elements which are the most widely diffused have small atomic weights.

The spin overwhelms the substance. That's very clearly what happened.

The noble gases, which reside on the East Coast of the periodic table, are its aristocrats - detached and aloof, never bothering to interact with the rabble of common elements that make up the vast majority of the world.

Most smoked salts are made with liquid smoke, which is a condensate, but really, really good smoked salt is literally smoked.

Atoms of Element 118 fill an outer shell with electrons, creating a special type of element called a noble gas. Noble gases are natural turning points on the table, ending one row and pointing to the next.

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.
