Question

h2o chemical bonding electron dot diagram​

Answer 1

is the answer of the question

Answer 2

In the diagram, provided above we get an idea about the structure of water molecules.

Oxygen atom has 6 valence electrons out of which 2 valence electrons are involved in bonding with the 2 hydrogen atoms. Therefore, a water molecule has 2 bond pairs of electrons and 2 lone pair (non-bonded) pairs of electrons.

So, we can say that the Lewis dot structure of of water molecule is:Therefore, corresponding to the question, we can that the correct Lewis dot structure of water molecules is number 3.
