G. N. Lewis

G. N. Lewis was an influential American chemist known for his work on chemical bonding and electron configuration. He introduced the Lewis dot structure, a visual representation that uses dots to show the valence electrons of an atom. This helps to understand how atoms bond with each other to form molecules. Lewis also proposed the concept of covalent bonds, where atoms share pairs of electrons. His contributions laid the groundwork for modern chemistry, helping scientists visualize and predict how different elements interact based on their electron arrangements.
