No such symbol as 'PA' on the Periodic Table. However I think you mean 'Pa' Protactinium'. 'P' could be the element phosphorus, but there is no element with the letter 'A'.
NB When writing up chemical symbols remember the rules;-
#1 Single letter elements , always have a CAPITAL letter.
#2 Two letter elements, always have a capital letter to start and the second letter is ALWAYS small case.
Here are some examples.
H - Hydrogen ,
O - Oxygen
N - Nitrogen
Na - Sodium (Nadium)
Cu - Copper (Cuprum)
Cl - Chlorine
If you do not correctly write the chemical symbol, there could be confusion as to what substance is being referred . e.g. 'CO' - Carbon Monoxide and 'Co' - Cobalt.
