Appearing as practical electronic components in 1962‚[7] early LEDs emitted low-intensity red light‚ but modern versions are available across the visible‚ ultraviolet‚ and infrared wavelengths‚ with very high brightness. When a light-emitting diode is switched on‚ electrons are able to recombine with holes within the device‚ releasing energy

The Biological Importance Of Water Water plays a huge role in our lives‚ the molecule which is comprised of two atoms of hydrogen and one atom of oxygen bonded together has many complex properties. The molecule maintains a bent shape due to its tetrahedral arrangement and the negative lone pair of electrons on the oxygen. The electrons from both hydrogen and oxygen are joined covalently but the difference in electronegativity lets the electrons from hydrogen get pulled slightly toward the oxygen
