Answer:

Gold has a symbol that starts with letter different from the first one in its name.

Explanation:

The element symbol is the abbreviation of the name of the element. It is usually the first or the first two letters of the element name. The first letter is written in upper case and the second letter in lower case. The symbol for the following elements are given below:

• Zinc- Zn

• Aluminium-Al

• Rhenium- Rh

There are some symbols of elements which are taken from their Latin root names. For example, the symbol of gold is Au. It is taken from the first two letters of the Latin name 'Aurum'. Other elements which follow the Latin root names are;

• Silver(Argentum)-Ag

• Lead(Plumbum)-Pb
