Answer is "slightly
negative".
Explanation
In water molecule, there are 3 atoms which belonged to 2 elements. They are 2 H
atoms and 1 O atom. Oxygen atom is more electronegative than H atom. Hence,
Oxygen atom in the water molecule gets a slightly negative charge
on it.
What is electronegativity?
Electronegativity is a value that tells us how an atom can attract electrons
towards itself.
It helps us to tell the nature of molecule (as polar or non-polar) and the
nature of the bond between atoms (as ionic or covalent).
If the electronegativity is high, then the attraction to the electrons is high
unless the attraction to the electrons is low.
If the attraction towards electrons is high, then that atom gains a negative
charge on it.
