Question

the diagram shows the structure of a water molecule. which allows the three atoms in a water molecule to stay together?

covalent bonds formed by shared electrons between atoms
covalent bonds formed by electrons that transfer between atoms
ionic bonds formed by electrons that transfer between atoms
hydrogen bonds formed by only the electrons of hydrogen atoms

human blood has a ph of 7.4. how do buffers in the blood affect the ph? * blood ph regulation at rest

Explanation:

A water molecule consists of two hydrogen atoms and one oxygen atom. Covalent bonds are formed when atoms share electrons. In a water - molecule, the hydrogen and oxygen atoms share electrons to form covalent bonds, which hold the three atoms together. Ionic bonds involve the transfer of electrons, and hydrogen bonds are weaker attractions between molecules, not what holds the atoms within a single water molecule together.

Answer:

covalent bonds formed by shared electrons between atoms
