Question

In the present periodic table containing 118 elements:

How many elements are represented by a symbol beginning with Z?

Answer 1

The symbols of the elements in the periodic table are determined by the International Union of Pure and Applied Chemistry (IUPAC).

• In most cases, the symbols are the first or the first two letters of the element.
• In a few cases, the symbols are derived from the Latin names of the element.
• For example symbol for oxygen is O, and the symbol for cobalt is Co.
• For example, the symbol of silver is Ag, which is derived from its Latin name, Argentum.
• So, the elements in the periodic table with symbol starting with the alphabet Z is Zinc (Zn) and Zirconium (Zr).

Two elements are represented by a symbol starting with Z.
