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 A NEGATIVE CHARGE.
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.
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.
Neither. Molecules are electrically neutral, meaning that they have no net charge.
MOLECULES that have an uneven pattern of electric charge (more positive in one area; more negative in another) are said to be
No, they have neither positive or negative charge.
No, the answer would be polar molecules
Molecules that are most affected by microwaves are polar molecules. One end has a positive charge and the other a negative charge.
atoms and molecules are alike cause they both have a negative charge
A polar molecule is composed of a positive charge and a negative charge.
either negative or positive charge always
Atoms consist of electrons (negative charge), protons (positive charge), and neutrons (neutral charge), while molecules consist of atoms.
You are describing polar molecules, of which water is probably the most well known.
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.
its always zero
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.
The total electric charge is always zero.
chloride ions have a negative charge... hydrogen ions have a positive charge... positive and negative means attraction
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.
Molecules that have a positive charge collect electrons. This because they have more protons than electrons and positive charge attract negative charged electrons.
Any chemical species can have a positive or negative charge (though atoms and molecules with a charge are technically called ions).
Ions are molecules which have gained (negative) or lost (positive) an electron. Positive Charge are called Cations. Negative Charge are called Anions.
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.
The oxygen atom in a water molecule has a slight negative charge.
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.
