🔥EXPLANATION🔥: a covalent bond relies on the electrons in atoms. the electrons in the atom are first taught as the bohr model (definite points that orbit the nucleus), following the octet rule, as demonstrated in the second slide. however, this understanding is oversimplified, and in reality, electrons exist in orbitals that vary in shape and density. the shapes of s, p, and d orbitals are demonstrated in the first slide. . . . . . #chemistrymemes #sciencememes #chemistry #periodictable
