All isotopes have the same natural abundance.
There are more than 100 chemical elements that are identified in nature. The chemical symbols of the elements are denoted by either one or two letters. For
example, the element oxygen is denoted by the letter
. If the symbol has two letters, the first letter is always capitalized and the second is lowercase. For
example, the symbol for the element helium is
The periodic table is the tabular arrangement of all the chemical elements that have been identified. The elements are arranged according to their atomic numbers
and denoted by their symbols. This arrangement places elements of similar properties next to each other in the table. For example, metals are located on the left
hand side and nonmetals are located on the righthand side. Semimetals (metalloids) are placed between the metals and nonmetals, and have properties
intermediate between metals and nonmetals.
Identify the chemical symbols corresponding to each element.
Drag the appropriate labels to their respective targets.
What a chemical symbol is
A chemical symbol is shorthand for the name of an element. It uniquely identifies the element. The chemical symbol may be either one or two letters.
If the symbol is two letters, the first letter is capitalized and the second is lowercased.
For example, the chemical symbol for sulfur is
, and the symbol for silicon is
In some cases, the chemical symbol is derived from the Latin or Greek name of the element. For example, the symbol of gold,
, is derived from its
, meaning “shining dawn.”
