Molecules are neutral, they do not have an overall charge, although in many cases there will parts of a molecule which have a negative charge and other parts that have a positive charge (for example, in a water molecule, the oxygen atom has a negative charge and the two hydrogen atoms have a positive charge).

DNA molecules have what kind of charge?
DNA MOLECULES HAVE A NEGATIVE CHARGE.
Where is the majority of negative charge on the water molecule?
Water molecules consist of hydrogen molecules and oxygen molecules. Most of the negative charge comes from the oxygen molecules while the hydrogen molecules carry the positive charge.
How do polar molecules differ from nonpolar molecules?
Polar molecules have positive charge on one side and negative charge on other side. Non polar molecules have covalent bond and do not have positive and negative charge on one or other side of the molecule.
Do molecules have positive or negative net charge?
Neither. Molecules are electrically neutral, meaning that they have no net charge.
What molecules have an uneven charge with more negative charge on one side?
MOLECULES that have an uneven pattern of electric charge (more positive in one area; more negative in another) are said to be
Do non-polar molecules have a charge?
No, they have neither positive or negative charge.
Do nonpolar molecules have a slight negative charge on one end and a slight positive charge on the other?
No, the answer would be polar molecules
Which molecules are most affected by microwaves?
Molecules that are most affected by microwaves are polar molecules. One end has a positive charge and the other a negative charge.
How are atoms and molecules alike?
atoms and molecules are alike cause they both have a negative charge
Characteristics of polar molecules?
A polar molecule is composed of a positive charge and a negative charge.
What is the charge of an ion?
either negative or positive charge always
How are atoms different from molecules?
Atoms consist of electrons (negative charge), protons (positive charge), and neutrons (neutral charge), while molecules consist of atoms.
What molecules have an uneven charge with more negative charge on the side and more positive charge on the other?
You are describing polar molecules, of which water is probably the most well known.
Is electrons has a negative charge?
Electrons have a negative charge. Protons have a positive charge, and neutrons have a neutral charge. Added: Electrons always have a negative charge, value: minus 1.602*10-19 Coulomb.
Is the charge of a compound always negative or positive?
its always zero
How do water molecules attract other water molecules?
The Oxygen atom in water hogs electrons from the Hydrogen atoms, giving it a negative charge, and the hydrogens a positive charge. Because of this, water molecules have positive and negative ends. The positive Hydrogens in one molecule will attract the negative Oxygen in another.
What is the total electric charge on molecules and compounds?
The total electric charge is always zero.
Can a positively charge hydrogen ends of water molecules attract chloride ions?
chloride ions have a negative charge... hydrogen ions have a positive charge... positive and negative means attraction
How is paper chromatography different from electrophoresis in separating molecules?
In paper chromatography molecues are separated by capillary action, which is the attraction forces between the molecules and the paper. In elecrophoresis molecules are separated by charge. The samples are placed at one end of a gel, and a negative charge is applied to the other end of the gel. The molecules are then attracted to and migrate toward the negative charge being applied.
Which molecules collect electrons?
Molecules that have a positive charge collect electrons. This because they have more protons than electrons and positive charge attract negative charged electrons.
What species has a positive charge?
Any chemical species can have a positive or negative charge (though atoms and molecules with a charge are technically called ions).
What are positively and negativity charged ions?
Ions are molecules which have gained (negative) or lost (positive) an electron. Positive Charge are called Cations. Negative Charge are called Anions.
Why does water cling to polar molecules?
Water is polar because of its unequal sharing of the electron which makes hydrogen slightly positive in charge and oxygen slightly negative in charge. When this happens, the slightly positive hydrogen atoms attract other slightly negative molecules, and thus, attracting other polar molecules. This cannot happen with nonpolar molecules because their charge is zero.
What is true about water molecules?
The oxygen atom in a water molecule has a slight negative charge.
A molecule that has a partial positive charge on one side and a partial negative charge on the other side is?
A polar molecule...such as water. The oxygen molecules pulls the electrons closer, causing the oxygen to have a more negative charge and the two hydrogen atoms to have more positive charges. this is very important in the bonding of water molecules to other water molecules.
