I know throwing a Sleep Seed will put the opponent to sleep (unless it dodges/catches it or something). I believe there's also a Slumber Orb.
there are lots the top ones would be sleep powder and sing or lulaby only a few Pokemon know them like butterfree or bulbasaur but only jet Jackson learns lulaby
Spore is a move that puts Pokemon to sleep and ends with the letter E.
Hypnosis, sleep powder, stuff like that...
a sleepy Pokemon is a Pokemon that has been hit by a move such as sleep powder and may go to sleep. or maybe it has a personality that is sleepy.
Buy about 50 Ultra Balls. Get a Pokemon with a Sleep-inducing move such as Sleep Powder or Sing. If you have a Pokemon under level 50 with Electric or Fire-type moves, that will also work well in lowering Articuno's HP. Once the HP is down to red or a small amount of yellow, put Articuno asleep and chuck Ultra Balls like crazy. If it wakes up, put it back to sleep again. Eventually you'll catch it.
Yes, spore does put a Pokemon to sleep. It will incduce sleep every time.
There are no items that can put Pokemon to sleep, only moves like hypnosis and sleep powder.
AnswerWhile a number of TMs in Pokemon Silver take advantage of the Sleep status, only one move actually puts Pokemon to sleep. TM44 - Rest, when used by a Pokemon, will put the user Pokemon to sleep for a number of turns. No TMs available in Pokemon Silver will put your opponent to sleep.
