What is the type of chemical bond in the Cl₂ molecule? what do you know about this type of connection?

In the chlorine molecule there is a covalent non-polar bond. Covalent bond – formed as a result of overlapping clouds of pairs of valence electrons. The polarity of the bond is presented in the form of an uneven distribution of electron density through the different electronegativity of the atom. Two bonds are distinguished behind this sign: polar – the molecule consists of different atoms (НСl, NaI, LiF) – electron clouds are located asymmetrically to each atom; non-polar (H2, Cl2, O2, Br2, I2, F2, N2) – electron clouds are placed symmetrically to each atom.
