When balancing a chemical equation, you multiply the subscripts in a chemical formula times the coefficient in front of the formula to get the total number of atoms of each element.

104 Unq Unnilquadium, usually known as Rf Rutherfordium
As of today (Mar 7, 2011) Rhodium is selling for $2380 an ounce. At its peak before the recession, rhodium sold as high as $10,010 an ounce (May '08)! See the related link for a chart of a updated value.
1Cl2 3F2 is not a valid chemical formula. In chemical formulas, the number comes before the element symbol, and subscripts are used to indicate the number of atoms present.
Prefixes in chemical names indicate the number of atoms of each element present in the molecule before the main part of the name. They provide information about the composition and structure of the compound.
The chemical symbol for chlorine is Cl. And before you ask individually about every chemical element, allow me to refer you to the periodic table of elements (look it up on google) which gives all of them.
When an element burns, its mass remains the same. The burning process involves a chemical reaction that rearranges the atoms of the element, but the total mass of the element before and after burning remains constant, according to the law of conservation of mass.
No. Compounds have unique chemical and physical properties different from the elements of which they are made.
Robert Boyle was the first to define an element as a substance that is unable to be broken down into smaller substance by chemical reaction.
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
