The chemical bond between hydrogen and oxygen atoms in a water molecule forms by a shared pair of electrons between hydrogen and oxygen
<h3>Further explanation</h3>Chemical bonds that occur between 2 atoms can consist of:
- 1. ionic bonding
The bonding that occurs due to electron handover. It can occur in metal and non-metal atoms. To get stability, atoms release or bind electrons to get stable electron regulation from noble gases
- 2. covalent bonding
The bonding that occurs due to the shared use of electron pairs
The two bound atoms contribute their electrons to produce bonds
Generally occurs in non-metallic elements
In the water molecule itself:
Electron configuration H = 1s²
Electron configuration O = 1s² 2s² 2p⁴
H atoms need 1 electron to be stable like the duplet configuration of the noble gas element He and O atoms need 2 electrons to be stable like Ne
So that the O and H atoms contribute their electrons and covalent bonds are formed
The occurrence of polar covalent bonds of water molecules is the electronegative difference between two bonding atoms.
The attraction of electrons (electronegativity) from O atoms in water molecules causes electrons to be attracted more to O atoms and electrons are not evenly distributed so that negative charge/poles appear on O atoms and positive charge/poles are at 2 Hydrogen atoms
