According to the Lewis model, what is a chemical bond?
Solution 6E Step 1 of 1 According to the Lewis theory, atoms tend to form a bond in order to lower their Energy values. Atoms have high Energy values because of their incomplete electronic configuration, that make them unable to resemble the stability of noble elements. When they form a bond , atoms achieve a better stability, that make every single atom similar to the closer noble element in the periodic table. For Example Sodium (Na) will tend to resemble Neon (Ne), that is the most closer noble element to it; for the same reason Chlorine (Cl) will tend to resemble Argon (Ar). In order to resemble form a bond, atom can lose/acquire electrons or alternatively, the can share electrons. We can distinguish three major chemical bonds 1- Ionic bond, that is based on lose or gain of at least one electron between two atoms that tendo to transform in their respective ions 2- Covalent bond, that is based on electron sharing between two atoms 3- Metallic Bond, that is based on the formation of a lattice formed by metallic ions in which valence electrons float forming a sort of “sea” of negative charges delocalized in the whole lattice.
