JILA researchers have, for the first time, trapped and cooled single alkaline-earth atoms. (Related: "The God Particle"). The needles are about 2 millimeters (0.08 in.) At 38 protons and 215 billionths of a millimeter across, strontium atoms are relatively large by comparison. Answer (1 of 10): I'm glad you used the word "image" instead of "photograph". Simple proportionality establishes that the atom is circa one tenth of one millimetre in diameter, which given our understanding of the physicality of atomic structures does not accord. When I was young and in elementary school, teachers would say things like, "We know atoms exist, but we will never be able to see them." I thought that was interesting, why should that be? All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge - a cation, which combines with anions to form salts.
