An element is a pure substance made up of atoms with the same atomic number. A compound is a pure substance made up of two or more elements. The smallest unit of a compound is a molecule. A mixture, on the other hand, is a substance formed ...
The main classifications of matter include the categories element and compound, either of which may also be called a substance (which is a less specific term), and mixture, of which there are also many sub-categories.Definition of a (Chemical) Mixture:...

If you could look at a polymer chain close up, you would see that the visual structure and physical properties of the molecule chain mimic the physical properties of the polymer. For example, if a polymer chain comprises tightly twisted bonds between monomers that are difficult to break, the ...
Through quantitative live-cell imaging, we show that TauC3 has a drastically reduced dynamics of its microtubule interaction. Single-molecule tracking of tau confirmed that TauC3 has a longer residence time on axonal microtubules. The reduced dynamics of the TauC3-microtubule interaction correlated ...
Today, a mole isAvogadro's numberof particles, which is exactly 6.02214076×1023. For all practical purposes, the mass of one mole of a compound in grams is approximately equal to the mass of one molecule of the compound in daltons. ...
