what kind of bond holds the hydrogen to the oxygen in one water molecule??

it is a polar covalent bond.

The bond that holds the hydrogen to the oxygen in a water molecule is called a covalent bond. A covalent bond occurs when two atoms share electrons between them. In the case of water, oxygen and hydrogen atoms share electron pairs to form a stable molecule.

To determine the type of bond between atoms in a molecule, you can follow these steps:

Step 1: Identify the atoms involved in the bond. In this case, it is hydrogen and oxygen.

Step 2: Determine the valence electrons for each atom. Valence electrons are the outermost electrons of an atom that participate in bonding. Hydrogen has one valence electron, while oxygen has six.

Step 3: Calculate the number of missing or extra electrons needed for each atom to achieve a stable electron configuration. Hydrogen needs one more electron to complete its valence shell, while oxygen needs two electrons to fill its valence shell.

Step 4: Determine if the atoms share, gain, or lose electrons to achieve stability. In the case of water, oxygen shares two electrons with two hydrogen atoms. Each hydrogen atom shares one electron with the oxygen atom, allowing both hydrogen and oxygen to complete their valence shells.

Step 5: Based on the sharing of electrons, identify the type of bond. In this case, since electrons are shared between hydrogen and oxygen, it is a covalent bond.

So, the bond that holds the hydrogen to the oxygen in a water molecule is a covalent bond.
