The molecule of an element can be represented using a chemical formula by stating the symbol of the single type of atom present in it, along with its count. For instance, the molecule of chlorine (Cl) has two atoms. Therefore, it is represented by the chemical formula Cl2. The molecule ...

Anempirical formula consists of symbols representingelementsin acompound, such as Na forsodiumand Cl forchlorine, and subscripts indicating the relative number ofatomsof eachconstituentelement. (A subscript is not used, however, unless the number is more than one.) Thus,benzeneis represented by the...
For example, each oxygen molecule is made up of 2 oxygen atoms, and the chemical formula of oxygen is O2 Diatomic molecules, chemical forms: O2 (oxygen), N2 (nitrogen), H2 (hydrogen) F2 (fluorine gas), Cl2 (chlorine) and Br2 (liquid bromine) Chemical formula for polyatomic molecules: ...

The correct formula is ZnS. Answers in Appendix E 1. Write formulas for the binary ionic compounds formed between the following elements: a. potassium and iodine d. aluminum and sulfur b. magnesium and chlorine e. aluminum and nitrogen c. sodium and sulfur 2. Name the binary ionic compou...
In molecular formulae, the elements are denoted by their respective symbols (as in the periodic table) and the number of atoms of each element in the molecule is written in subscript. For example- the molecular formula for glucose is C6H12O6. Empirical Formula: The empirical formula of a ...
The chemical formula of table salt or sodium chloride is: NaCl There are one sodium atom and one chlorine atom in each molecule. Note there is no subscript for the number "1." Types of Chemical Formulas While any expression that cites the number and kind of atoms is a chemical formula, ...
