How many sigma bonds are there in o3?
Not too many people know that in chemistry, sigma bonds (? bonds) are the strongest type of covalent chemical bond. What does this mean? They are formed by head-on overlapping between atomic orbitals. It is important to know that there are 2 sigma bonds in O3. Needless to say, the electrons in these bonds are sometimes referred to as sigma electrons. It is widely known the fact that the symbol ? is the Greek letter sigma.
