3. which of the following is correct regarding the chemical bond between
hydrogen and
oxygen atoms in a water molecule?
forms by a shared pair of electrons between hydrogen and oxygen
o results in an unusually strong bond
results in a nonpolar molecule of water
forms between the neutral poles of hydrogen and oxygen

The chemical bond between hydrogen and oxygen atoms in a water molecule forms by a shared pair of electrons between hydrogen and oxygen

Chemical bonds that occur between 2 atoms can consist of:

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

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
