Question

During the formation of covalent bond electron cloud of combining atoms

Answer 1

Answer:

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Answer 2

it is a special type of covalent bond between two atoms by which the atom which is more electronegative attracts more electrons from the bonded pair than the other atom.
