Which of the following statements best describes a water molecule?
|
|
Water has an overall positive charge
|
|
|
Water has an overall negative charge
|
|
|
The uneven sharing of electrons causes a slightly positive and negative side.
|
|
|
The even sharing of electrons.
|
Explanation:
Detailed explanation-1: -Since water is a nonlinear, or bent, molecule, the difference in electronegativities between the oxygen and hydrogen atoms generates the partial negative charge near the oxygen and partial positive charges near both hydrogens.
Detailed explanation-2: -Covalent bonds occur when two atoms-in this case oxygen and hydrogen-share electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge.
