'SN' in the Periodic Table are the two elemental symbols for 'sulphur(S)' and ''nitrogen(N)'.
So SN is some form of sulphur/nitrogen compound.
However, I think you mean 'Sn'.
'Sn' is the symbol for 'Tin'. 'Sn' is the Latin initials of 'Stanum', which is the Latin word for 'Tin'.
NB When writing up chemical/elemental symbols, be careful!!!!
Single letter symbols are ALWAYS a CAPITAL letter.
Two letter symbols are written ; first letter is a CAPITAL letter and the second letter is small/lower case.
This is the IUPAC Internationally recognised system, and as shown in the PERIODIC Table.
'Sn' is 'Tin'. The initials 'Sn' comes from the Latin word for tin, which is 'Stanum'.
