bonds are formed when the atomic of two non-metal atoms overlap, allowing electrons to be shared between them.
|
When atomic orbitals combine to form covalent bonds, they undergo a process called , where an s orbital mixes with one, two, or three p orbitals.
|
A bond is formed from one σ bond and one π bond.
|
