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.

A microscope (from the Ancient Greek: Î¼Î¹ÎºÏÏÏ, mikrÃ³s, small and ÏÎºÎ¿ÏÎµá¿Î½, skopeÃ®n, to look or see) is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes. The most common (and the first to be invented) is the optical microscope, which uses light to image the sample.
