WebThe 1,2,3-triazole scaffold was chosen as the primary component of the internucleotide linker because it can be easily synthesized via the copper(I)-catalyzed azide–alkyne 1,3-dipolar cycloaddition (CuAAC, “click”) reaction which is being widely utilized in nucleic acid chemistry. 11,49,51 Re(I)-carbonyl, on the other hand, was chosen as the metal … WebJohn Dalton. Modern Atomic Theory (John Dalton) Experiments with gases that first became possible at the turn of the nineteenth century led John Dalton in 1803 to propose a modern theory of the atom based on the following assumptions. 1. Matter is made up of atoms that are indivisible and indestructible. 2. All atoms of an element are identical. 3.

WebDalton's ideas proved foundational to modern atomic theory. However, one of his underlying assumptions was later shown to be incorrect. Dalton thought that atoms were the smallest units of matter −-− minus tiny, hard spheres that could not be broken down any further. This assumption persisted until experiments in physics showed that the atom was composed …
