What is Charge Density?
In electromagnetism, charge density is a measure of electric charge per unit volume of space, in one, two or three dimensions. More specifically: the linear, surface, or volume charge density is the amount of electric charge per unitlength, surface area, or volume, respectively. The respective SI units are C·m−1, C·m−2 or C·m−3.[1]Like any density, charge density can depend on position, but because charge can be negative - so can the density. It should not be confused with the charge carrier density, the number of charge carriers (e.g. electrons, ions) in a material per unit volume, not including the actual charge on the carriers.In chemistry, it can refer to the charge distribution over the volume of a particle; such as a molecule, atom or ion. Therefore, a lithium cation will carry a higher charge density than a sodium cation due to the lithium cation's having a smaller ionic radius, even though sodium has more electrons (11) than lithium (3).
Is an ion an or molecule that carries a charge?
A molecule hasn't an electrical charge. An ion has a positive charge (cation) or a negative charge (anion).
What is the majority of negative charge on the water molecule?
there has to be a negative charge in the molecule as there is a positive charge. there is a negative charge and when it and a positive charge gets together it forms something that makes the charge neutral
How does the composition of a water molecule affect its charge?
It makes the molecule polar
Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom the molecule is nonpolar.?
That statement is incorrect. HF is a polar molecule because fluorine is more electronegative than hydrogen, causing the electron density to be pulled closer to the fluorine atom. As a result, HF has a partial positive charge on the hydrogen atom and a partial negative charge on the fluorine atom.
Does a A molecule with a positive charge attracted to another molecule with a positive charge?
Nope

Is perc polar?
Yes, perchloroethylene (perc) is a polar molecule. This is because the molecule contains chlorine atoms with a higher electronegativity than carbon atoms, resulting in an uneven distribution of electron density. This creates a partial positive charge on the carbon atoms and a partial negative charge on the chlorine atoms, making the molecule polar.
Is an ion an or molecule that carries a charge?
A molecule hasn't an electrical charge. An ion has a positive charge (cation) or a negative charge (anion).
Does h2 have a net charge?
No, h2 does not have a net charge. It is a neutral molecule.
What is the overall charge on a water molecule?
It's not an ionic compound.
Do molecule have charge?
No. Molecules do not have charge. Ions have a charge. If a compound is has more than one atom and a charge, then it is a poly-atomic ion, not a molecule.
What is the charge density for a conductor?
The charge density inside a conductor is always zero
What is the charge of a nitrite molecule?
-1 charge
Where is the density of electrons greatest in the water molecule?
The density of electrons in a water molecule is highest around/near the oxygen atom.
What is the majority of negative charge on the water molecule?
there has to be a negative charge in the molecule as there is a positive charge. there is a negative charge and when it and a positive charge gets together it forms something that makes the charge neutral
Is the charge on a diatomic molecule called the oxidation number?
No. The oxidation number is the charge on the atom of an element, or if the bonding is covalent, what that charge would be if that bonding were ionic. A "molecule" with an electrical charge would be a polyatomic ion, not a molecule.
