Question

Water, H2O, is a molecule made of oxygen and hydrogen. The bonds that hold water molecules together are due to shared electrons, and known as __________ bonds. In contrast, the bonds that hold NaCl molecules together are _________ bonds, arising from a charge difference between the atoms.

Answer 1

Answer: your first answer is covalent bonds the second is ionic

Step-by-step explanation:

I had this question

Answer 2

Covalent bond

ionic bond

Step-by-step explanation:

Water molecule is formed when two hydrogen atoms combine with one atom of oxygen. The bond through which these atoms are join together is called covalent bond.

The electrons are shared between these atoms but this sharing is not equal. the oxygen atom more strongly pull the electrons to wards itself and thus carry partial negative charge and hydrogen have partial positive charge.

Ionic bond:

The bond between sodium chloride is ionic. This bond is formed due to complete transfer of electron from sodium to chlorine.

Na⁺Cl⁻

The sodium atom carry positive charge and chlorine carry negative charge.
