Si is the symbol of element silicon.
The element that contains 14 protons in its atoms has the atomic number 14. On the Periodic Table, this element is silicon, Si.
The element Silicon is represented on the periodic table by the symbol Si.
'si' does stand for any chemical element!!!!! If you mean 'Si', then it is silicon. NB For single letter elemental symbols are ALWAYS a CAPITAL letter. For two letter elemental symbols, the first letter is always a capital letter amd the second letter is small /lower case. This is the International IUPAC standard, and as found in the Periodic Table. Hence, silicon is 'Si' , not 'si'
