As 'pt' it is neither an element nor a compound. If you mean 'Pt' ( Platinum) , then it is an elementasl metal , found in the Periodic Table. NB For elemental symbols , a one letter symbol is ALWAYS a CAPITAL letter. For a two letter symbol , the first letter is always a CAPITAL letter and the second letter is small/lower case. This is the recognosed international standard. Hence 'pt' does not exist , but 'Pt' is platinum.
