None of them. Cl is the symbol for an atom of chlorine. If it were a compound there would be at least one other symbol, and the same applies to a polar molecule. If it were a negative ion it would be Cl- with the negative sign as a superscript. Chlorine doesn't form positive ions in normal circumstances, but it would be Cl+ , again with the charge as a superscript.
Cl is the chemical symbol of chlorine.
Cl is the element Chlorine, a halogen.
Table salt is an ionic compound consisting of sodium and chlorine ions. Its chemical formula is NaCl. Note that "salt" is a general term for any compound consisting of positive and negative ions, so compounds such as MgBr2 are also known as salts.
a molecule with a difference in charge. i.e. if it is slightly more negative in one place than another you say it has a dipole. you label it with the greek symbol delta- delta+ the - at the more negative part of the molecule. i am looking at this from a chemistry angle.
AL has 3 more negative charges than positive ones
only compounds with the (aq) state symbol
An atom in an equaton is only the symbol of this element, not a molecule.
yes
The chemical formula of a compound states the number and types of atoms in each molecule of a compound.
Positive is usually indicated by the color red or by a "+" symbol. Negative is indicated by black or by a "-" symbol.
Positive is either red or has a "+" symbol.
Water is made up of 2 hydrogen molecules and one oxygen molecule. It's chemical name is dihyrogen monoxide. The overall compound has no charge, positive or negative, but at an atomic level the parts of the molecule have a slight charge. Hydrogen slightly positive, oxygen slightly negative. Think of it as the Disney Mickey Mouse symbol! Uniquely in water, these slight changes attract the opposing charged molecule in another compound. So the negative oxygen atom of one water molecule attract a positive hydrogen atom of another molecule. http://upload.wikimedia.org/wikipedia/commons/f/f9/3D_model_hydrogen_bonds_in_water.jpg These bonds give water molecules a bond with each other. It's why water beads together on glass. This bond can be broker very easily, eg by putting your hand in water. But if you are a very small insect, there will be enough of this "Surface Tension" force to support your weight.
The negative wire is the one with this symbol on the battery. (-) Positive is (+)
positive
S is the atomic symbol for sulfur, which is an element. A compound is a molecule that is composed of two or more different elements.
Yes.
The same as in many programming languages and other places where formulae are used. The negative sign can basically do one of the following: As a unary symbol (i.e., before a number), convert a positive to a negative, or a negative to a positive. For example, if "x" is positive, "-x" is negative, and vice versa. As a binary symbol (i.e., between two numbers), it means subtraction.
There is no standard for locating the positive or negative posts on a battery. You must look fot the " + " symbol on the battery. The positive post is slightly larger than the negative post.
Till date there is no symbol for acid and base but an acid molecule is ending with hydride ion(H negative) and a base is ending with hydroxide ion (OH negative).
