The eye is so complex that even Charles Darwin was at a loss to explain how it could have arisen. Now, it turns out that the evolution of the vertebrate eye got an unexpected boost—from bacteria, which contributed a key gene involved in the retina’s response to light.
WebThe geometries of molecules with lone pairs will differ from those without lone pairs, because the lone pair looks like empty space in a molecule. Both classes of geometry are named after the shapes of the imaginary geometric figures (mostly regular solid polygons) that would be centered on the central atom and have an electron pair at each vertex. WebIn BeF 2, Be is surrounded by 2 electron bond pairs, hence the molecule is linear. On the other hand in SF 2 the central atom S is surrounded by 2 bond pairs and 2 lone pair …
