covalent
|
|
|
ionic
|
|
|
hydrogen

|
None of the above

Explanation:
Detailed explanation-1: -Strong linkages-called covalent bonds-hold together the hydrogen (white) and oxygen (red) atoms of individual H2O molecules. Covalent bonds occur when two atoms-in this case oxygen and hydrogen-share electrons with each other.
Detailed explanation-2: -Answer and Explanation: In one molecule of water, two hydrogen atoms are bonded to one oxygen atom by polar covalent bonds.
Detailed explanation-3: -Water is a Polar Covalent Molecule The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
