Each element is given a symbol (a letter or a pair of letters where the first one is always a capitol letter and the second one is always a small letter). For instance the letter for Hydrogen is an 'H' and for Oxygen is an 'O'.
When describing the formula for a chemical compound you use these symbols to say what elements it is made of and you follow each element with a number if there is more than one atom of that element in the compound.
For instance water is made of one atom of Oxygen and two atoms of Hydrogen and therefore its chemical formula is: H2O
This symbolic representation is known as a chemical formula.
A group of symbols that represent a compound is a Coefficent
This is a chemical formula; for example sodium chloride is NaCl.
This representation is called a chemcial formula
This representation is called a formula.
A Chemical Formula
i have no idea i need help......
This is a chemical formula.
The combination is known as a chemical formula.
The chemical symbol is used only for chemical elements; the chemical formula is for molecules. Ex.: Na is the chemical symbol of sodium and NaCl is the chemical formula of sodium chloride.
Stoichiometry
Chemical formula
A shorthand representation of the composition of a substance using atomic symbols and numerical subscripts is called a chemical formula.
A combination of chemical symbols that show what elements make up a compound and the number of atoms of each element in the smallest unit of the compound is a chemical formula.
This is a chemical formula; for example sodium chloride is NaCl.
This is a chemical formula; for example sodium chloride is NaCl.
Its called Chemical formula
This combination of symbols is known as a chemical formula.
The shorthand way to write a compound is by using chemical formulas or symbols. For example, water is written as H2O, where "H" represents hydrogen and "O" represents oxygen. Another compound, carbon dioxide, is written as CO2, where "C" represents carbon and "O" represents oxygen.
Search in a periodic table the chemical symbols of all chemical elements.
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.
