Covalent bonds. Silicon, carbon, germanium, and a couple of different components structure covalently reinforced solids. In these components there are four electrons in the external sp-shell, which is half filled. ... In the covalent bond a particle shares one valence (external shell) electron with every one of its four closest neighbor iotas.
Covalent bonds. Silicon, carbon, germanium, and a few other elements form covalently bonded solids. In these elements there are four electrons in the outer sp-shell, which is half filled. ... In the covalent bond an atom shares one valence (outer-shell) electron with each of its four nearest neighbour atoms.
Standing waves can be thought of as a sin wave and a cos wave overlapping each other. They go in different direction hence Cis correct
Wave interference can be thought of as the opposite of destructive ---> constructive anda hencd meet and interact on the same medium such that answerBis correct
