Because of the electronegativity, the electrons in the bond will be more attracted to the electronegative atom than to the hydrogen atom. Therefore, hydrogen atom will get a partial positive charge, whereas the more electronegative atom will get a partial negative charge.
Definition of telescope for Students. : a piece of equipment shaped like a long tube that has lenses for viewing objects at a distance and especially for observing objects in outer space.
A transparent structure behind the iris of the eye that focuses light entering the eye on the retina. A piece of glass or plastic shaped so as to focus or spread light rays that pass through it, often for the purpose of forming an image. A combination of two or more such lenses, as in a camera or telescope. Also called compound lens. A device that causes radiation to converge or diverge by an action analogous to that of an optical lens. The system of electric fields used to focus electron beams in electron microscopes is an example of a lens.
