The relative size of atoms can also be studied by measuring the radii of their ions. The first ionic radii were obtained by studying the structure of LiI, which contains a relatively small …
WebAn axon with a larger diameter offers less resistance to the movement of ions down the axon, causing ions to move faster down the axon and causing the action potential to be conducted faster. Let me show you the way I think about this by just considering a single sodium ion that's entering an axon through a voltage-gated sodium channel. WebSep 13, 2007 · Text Size. Anatomy of an Ion Engine. 09.13.07 . ... The ions are generated in a region of high positive voltage and the accelerator grid's voltage is negative, and since opposite charges attract, the positive xenon ions are attracted toward the accelerator grid and are focused out of the thruster through the apertures, creating thousands of ion ...
