Question
How many lone pairs of electrons does oxygen have in a water molecule?Group of answer choices1642
Solution
In a water molecule (H2O), the oxygen atom shares one pair of electrons with each hydrogen atom to form two covalent bonds. This leaves two pairs of electrons on the oxygen atom that are not involved in bonding. These are called lone pairs. So, oxygen has 2 lone pairs of electrons in a water molecule.
