Ion Channels: Structure and Function. Ion channels are membrane protein complexes and their function is to facilitate the diffusion of ions across biological membranes. Membranes, or phospholipid bilayers, build a hydrophobic, low dielectric barrier to hydrophilic and charged molecules. They are electrical insulators.
The inert gas xenon (chemical symbol Xe) has an atomic number of 54, and it has 54 protons in its nucleus. The number of neutrons varies, however.
Xenon is one of the heaviest gases; one liter of xenon weighs 5.842 grams. Uses: Xenon gas is used in electron tubes, bactericidal lamps, stobe lamps, and lamps used to excite ruby lasers. Xenon is used in applications where a high molecular weight gas is needed.The perxenates are used in analytical chemistry as oxidizing agents. Xenon-133 is useful as a radioisotope.enon is one of the heaviest gases; one liter of xenon weighs 5.842 grams.
