Quotes & Sayings About Elements And Compounds

When my world gets reset to zero, my starting post is blood. Specifically, the elements of it, the working compounds that make it what it is. Red cells, white cells, DNA, plasma full of proteins, enzymes, antibodies, minerals, electrolytes - all the things that when poked and prodded right tell you just about everything you want to know about a person. Fascinating stuff, and a little freaky, when you think about it. Blood was where I returned to after the accident that smashed my knee. It was where I went when I got out of prison. It was where I was when Mercy fell into my lap. Now it seemed, blood was my whole reason for being. — L.J. Hayward

With the exception of autotrophic bacteria, the green, or chlorophyll-bearing, plants are the only living forms on this planet capable of synthesizing organic matter out of inorganic elements and simple compounds. — Selman Waksman

Originally, the atoms of carbon from which we're made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life - the carbohydrates, amino acids, proteins, and lipids - is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air. — Michael Pollan

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. — Johannes Stark

In deriving a body from the water type I intend to express that to this body, considered as an oxide, there corresponds a chloride, a bromide, a sulphide, a nitride, etc., susceptible of double compositions, or resulting from double decompositions, analogous to those presented by hydrochloric acid, hydrobromic acid, sulphuretted hydrogen, ammonia etc., or which give rise to the same compounds. The type is thus the unit of comparison for all the bodies which, like it, are susceptible of similar changes or result from similar changes. — Charles Frederic Gerhardt

Today these four crops account for two thirds of the calories we eat. When you consider that humankind has historically consumed some eighty thousand edible species, and that three thousand of these have been in widespread use, this represents a radical simplification of the human diet. Why should this concern us? Because humans are omnivores, requiring somewhere between fifty and a hundred different chemical compounds and elements in order to be healthy. — Michael Pollan

The only difference between elements and compounds consists in the supposed impossibility of proving the so-called elements to be compounds. — Wolfgang Ostwald
