Question

Number of covalent bonds present in water molecule are______________​

Answer 1

Answer:

For completing its octet oxygen share its one electron with 1 hydrogen and 2nd electron with 2nd hydrogen atom.

So there are 2 covalent bonds formed.

Explanation:

A water molecule is represented by H2O. It means that there are 2 hydrogen and 1 oxygen atom present in 1 molecule of it.  

In Hydrogen atom there are 1 molecule present and it is an exceptional case so to complete its octet there must be 2 electrons in the outermost shell.  

And in case of oxygen there must be 2 electrons to fill its outermost shell and for this 2 hydrogen atom are requited that is the reason why the formula of is H2O.

Answer 2

Answer:

two covalent bonds

Explanation:

How many covalent bonds hold the water molecule together? A: The oxygen atom shares one pair of valence electrons with each hydrogen atom. Each pair of shared electrons represents one covalent bond, so two covalent bonds hold the water molecule together.
