Only (1) is natural, Ali; like most single-word adjectives, -ed particles assume the attributive position: 'a tired man', 'an energized committee', 'a rejected suitor'. There is no reason why irregular forms should be excepted: 'a strung guitar', 'a given proposition'.
There are probably some (which slip my mind) that are more common or only possible predicatively; and there are certainly a number that cannot be used as adjectives at all: X a 'been' event? X a 'talked' story?
