What is "covalent"

Usage examples of "covalent".

Now, somewhere along the line, when these guys were trying to design a plasmid to change covalent chlorine to ionic, they had to consider the possibility of making it go the other way.

The difference is that covalent chlorine is more reactive, it has these big electron clouds that can fuck up your chromosomes.

The difference between that and table salt is that table salt is inorganic, ionic chlorine - soldiers without a boat, with no ammunition - and this other stuff is organic, covalent chlorine - bad stuff.

But if you want to manufacture a whole stinking catalog of industrial chemicals, you have to convert ionic chlorine into the covalent variety.

The ionic chlorine turns into the covalent kind, which is what you want.

Cray supercomputer, or something, and did some kind of heavy quantum mechanics, worked out a rough numerical-solution Hamiltonian for chlorine, devised some kind of transition state between covalent and ionic, figured out a way to introduce an electron into those chlorines to make them ionic again.

This was inorganic chlorine, the safe kind, not the bad covalent stuff we were looking for.

Because a whole industry - most of the chemical industry - is founded upon a single reaction: the Chloralkali process - turning salt water into covalent chlorine.

We, in brilliant contrast, are completely organized structures, squirming with information at every covalent bond.

Ressler recognizes: Linus Pauling, Nobel laureate, supreme figure of American chemistry, he of vitamin C and the covalent bond, structural elucidator of any number of organic molecules, and nip-and-tuck runner-up to the three-dimensional solution of DNA.

Carbon materials are the strongest in nature, both because of the tremendous strength of the -carbon-carbon covalent bond and because carbon likes to arrange itself in triangles and hexagons, which are the stablest geometric structures possible.

To break it, you have to break a covalent bond, and that's not an easy thing to do.

What he didnt expect was that the drug seemed to form a loose covalent bond with both glutamate and gamma-aminobutyric acid, two of the major inhibitory agents in the brain.

He pointed to a diagram of a molecule shaped like a figure eight on its side, with some of its edges highlighted in blue for double covalent bonds.
