What are chemical symbols and chemical formulas?
A chemical symbol is a one- or two-letter designation of an element. A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements. Some elements have symbols that derive from the Latin name for the element.
How do you write the chemical symbol of an element?
Each element is given its own chemical symbol, like H for hydrogen or O for oxygen. Chemical symbols are usually one or two letters long. Every chemical symbol starts with a capital letter, with the second letter written in lower case. For example, Mg is the correct symbol for magnesium, but mg, mG and MG are wrong.

What do chemical symbols identify?
In this lesson you learned that a chemical symbol is a shorthand way to represent an element and that each element on the periodic table has a unique chemical symbol. Chemical symbols are used to standardize the ‘language of chemistry’ and to identify elements and atoms in a chemical formula easily.
What are the symbols used in chemistry?
Chemical Symbols and Formulas. To illustrate chemical reactions and the elements and compounds involved in them, chemists use symbols and formulas. A chemical symbol is a one- or two-letter designation of an element. Some examples of chemical symbols are \\(\\ce{O}\\) for oxygen, \\(\\ce{Zn}\\) for zinc, and \\(\\ce{Fe}\\) for iron.
What are some examples of compounds in chemistry?
Examples of Compounds. Examples of compounds include table salt or sodium chloride ( NaCl , an ionic compound), sucrose (a molecule), nitrogen gas (N 2, a covalent molecule), a sample of copper (intermetallic), and water (H 2O, a covalent molecule).
