A symbol is a shortened form of the name of an element. Mostly we use the first letter of the element. In case the first letter of the element is same as another element then we take first two letter of the element. Some symbols are based on the old names or Latin name of the element.

The below table contains elements and their respective symbols:
$$\begin{array}{cc}\text{Element}& \text{Symbol}\\ \text{Copper}& \text{Cu}\\ \text{Cobalt}& \text{Co}\\ \text{Calcium}& \text{Ca}\\ \text{Silver}& \text{Ag}\end{array}$$ Copper has its symbol Cu derived from its Latin name Cuprum.
