Which atom would be neutral? 1an oxygen atom with 16 electrons, 18 protons, and 16 neutrons

2an oxygen atom with 4 electrons, 6 protons, and 4 neutrons

3an oxygen atom with 9 electrons, 8 protons, and 8 neutron

4an oxygen atom with 8 electrons, 8 protons, and 9 neutrons

an oxygen atom with 8 electrons, 8 protons, and 9 neutrons

Explanation:

A proton has a positive charge and an electron has a negative charge. Magnitude of both of these charges is same. So, we need the same number of electrons and protons to make the atom neutral.

Neutron is neutral, so we can safely ignore it in this question.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
