From the Periodic Table, and the IUPAC , (International Union of Pure and Applied Chemistry).
Single letter symbols are always written as a CAPITAL letter.
.e.g. Hydrogen is 'H'.
Two letter symbols are always written as first letter is a CPITAL letter and the second letter is always lower/small case.
e.g. Rubidium is 'Rb'.
NB There are NO three(3) letter symbols.
For many elements , their modern name does not follow their symbol letters.
e.g. Sodium is 'Na'.
This is because a lot of early known elements had Latin name, and the symbol follows the Latin name.
Sodium ; (Na ; Nadium)
Potassium ; (K ; Kalium)
Iron ; ( Fe ; Ferrum)
Copper ; ( Cu ; Cuprum)
Silver ; ( Ag ; Argentum)
Gold ; (Au ; Aurum)
Mercury ; (Hg ; Hydragyrum).
Tin ; (Sn ; Stannum)
Are just a few.
