Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The atom around which the electrons spend the most time will have a ____ charge, and the atom around which the electrons spend the least time will have a ____ charge.
A
slightly negative, slightly positive
B
only positive charge
C
only negative charge
D
neutral charge
Explanation: 

Detailed explanation-1: -As a result, the electrons are not shared equally. The atom around which the electrons spend the most time will have a slightly negative charge, and the atom around which the electrons spend the least time will have a slightly positive charge.

Detailed explanation-2: -However, the attractions of electrons is sufficiently great so that, when covalently bonded to hydrogen, the electrons are not equally shared between the two nuclei. The electrons tend to spend more time around the oxygen nucleus and consequently less time around the hydrogen nucleus.

Detailed explanation-3: -1. The shared electrons in a water molecule spend more time near the oxygen atom than the hydrogen atoms. This is because the electrons are more attracted to the oxygen atom.

Detailed explanation-4: -In an atom, an electron is attracted to the nucleus by the “electromagnetic force", similar to your rubber band. Like your baseball, the faster the electron goes, the farther away from the nucleus it is. The electrons in an atom are moving pretty fast, so they are far away from the nucleus.
