I don't think we can do that. Although they're isoelectronic, they don't necessarily have the same properties because they have a different amount of protons. I believe you would go off of the previous noble gas, which is Neon, and then write the 3s orbital and 3p orbital. So, the configuration would be [Ne] 3s^2 3p^6.
It depends on the question if they ask for the ‘full ground state’ then you cant use the short hand, but if they don’t then you could write it as [Ar] to represent that it lost the 2 electrons from the +2 charge. If the question states you can use the abbreviation then yes, if not then no.
