Is water negatively charged?

Water is not negatively charged overall. It is a neutral molecule. However, it has a polar structure due to the difference in electronegativity between oxygen and hydrogen atoms. The oxygen end of the molecule has a partial negative charge, while the hydrogen ends have partial positive charges. This polarity allows water to form hydrogen bonds with other polar molecules. It does not form ionic bonds. Water's unique properties, such as high surface tension and the ability to dissolve many substances, are due to its polar nature.

Water is not negatively charged as a whole; it is a polar molecule with partial charges distributed unevenly.

Dipole Moment
The oxygen atom attracts electrons more strongly, creating a partial negative charge, while hydrogens have partial positive charges.

Neutrality Explained
These partial charges cause polarity but do not confer an overall negative charge to the water molecule.

A water molecule (H2O) is electrically neutral overall, meaning it has no net charge. It consists of two hydrogen atoms and one oxygen atom bonded covalently.

Polar Nature
Water is a polar molecule because of the unequal sharing of electrons and bent shape, resulting in a partial positive charge near hydrogen atoms and a partial negative charge near oxygen.

Misconception
Although water has regions of partial charges, the molecule as a whole is not negatively charged; it balances out to neutrality.

Water itself isn't negatively charged. It's actually a neutral molecule. But it's polar, which means the oxygen part has a bit of a negative charge and the hydrogen parts have a bit of a positive charge. This makes water really good at sticking to other molecules and dissolving things. It's like a tiny magnet. This is why water has such unique properties, like high surface tension. It's also why it's called the "universal solvent."
