Answer:
Water

Step-by-step explanation:
By observation at the image attached, each hydrogen atom has one electron, so in total the two hydrogen atoms contribute two electrons.
Then the oxygen atom has six (6) electrons, (3 lone pairs)
So, by covalent bonding, the two electrons are shared from hydrogen to Oxygen two make oxygen stable.
Since stable oxygen atom must have 8 electrons, so the 2 electrons from hydrogen move to the oxygen-6 to make oxygen-8.
As a result, a polar compound called Water is formed
