Question

How does the composition of a water molecule affect it's charge

Answer 1

Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge ( ) near the oxygen atom due the unshared pairs of electrons, and partial positive charges ( ) near the hydrogen atoms.

Answer 2

A molecule of water comprises two hydrogen atoms associated with an oxygen atom, that is, the formula of water is H2O. As there is a high difference in the electronegativity of both oxygen and hydrogen, therefore, there will be an unequal distribution of charge on a molecule of water as hydrogen will exhibit a positive charge, while oxygen will possess a negative charge. This will also make the molecule of water polar in characteristic.
