Every proton in an atom's nucleus gives it a positive charge equal to the negative charge from the electrons orbiting the nucleus. The charge of the entire atom is neutral if there are an equal number of protons and electrons. If there are an unequal number of protons and electrons, the net charge of the atom, which is now an ion, is plus or minus e for each extra or missing electron. For example if an atom has 6 protons and 4 electrons, it has a charge of plus 2e.
The oxygen atom is neutral.
Hydrogen has a positive charge.
The smallest whole bit of matter for elements is an atom, for compounds is a molecule, and for mixtures is a particle.
Sodium become a cation (positive charge) - Na+.
An atom is always neutral of charge, meaning ZERO. This is possible because of the equal numbers of (positive) protons and (negative) electrons, each plus charge is compensated by one (equally negative) minus charge.

This atom become a cation (positive).
Neutral or no charge.
The oxygen atom is neutral.
Hydrogen has a positive charge.
The charge of an atom as a whole is zero. We can give the charge of a nucleus. If any electron, negatively charged one, go out of atom then the atom gets positive charge and it is named as positive ion. Same way if excess electrons get cling with the neutral atom then the atom becomes a negative ion.
An atom that has the same amount of protons and electrons has no net charge and therefore is neutral.
Because protons (positive) are neutralized by electrons (negative).
Oxygen -2 Hydrogen +1
a partially negative charge.
