Incorrect. A particle has mass, and cannot attain light speed.

Should have said "charged particle" rather than "particle".

You were correct the first time.

Nothing with mass can attain light speed and it doesn't matter if it is

I think you need to clarify.. zero "rest mass"..

Nope, "mass" unqualified refers to rest mass and qualifiers only become
necessary if talking about other than rest mass.
