The bond formed when two electrons that are shared between two atoms are donated by only one of the atoms is

@Christianah, try to follow through with the explanation given below:
Covalent bonding is the type of bonding that involves sharing of electron between two atoms either of the same elements or atoms of different elements. Usually it takes place between non-metals, as seen in two molecules of Hydrogen, two H bonding together to form H2, two molecules of Cl to form, Cl2 etc Rememeber that the purpose of bonding is to attain the duplet or octet number for stability. However, Covalent bonding is divided into two, namely;
(i) Ordinary covalent bonding and (ii) Co-ordinate covalent bonding (Dative bonding).
If the lone pair of electrons needed for bonding to take place between the two atoms are donated by the two atoms involved in bonding, it is referred to as ordinary covalent. E.g H atom has 1 valence electron in its outermost shell, so it needs 1 more electron to attain the duplet state and become stable, so it looks for another atom that is also in need of 1 electron like itself, then comes another hydrogen atom. Both of them therefore bring one electron each and share so that at the end they are satisfied, thereby forming Hydrogen molecule, H2. i.e H + H = H2
On the other hand, if the lone pair of electrons needed for bonding to take place between two atoms are donated by only one instead of the two atoms, it is called Co-ordinate or dative bonding. E.g Ammonia bonds with Hydrogen ion to form Ammonium ion. i.e NH3 + H+ = NH4+

I hope this helps.
Thank you

explanation pls...this parts of chemistry is confusing
