no but you can trade Pokemon holding the items.

Yes, it is possible to trade items in Pokemon Pearl but, this is only allowed if you trade the item when it's attached to a Pokemon. If you are trading with a friend and don't want him to have your Pokemon just trade back.
That trade is not possible. Soulsilver cannot recognize Pokemon from newer versions.
Yes, it is possible to trade your UK Pokemon from Diamond into the Japanese Pokemon Black version. However, you need to beat the whole game in Pokemon Black & White to be able to trade Pokemon from the other generations.
You can trade the DS Pokemon games onto Pokemon Black and White when you have the national pokedex and have found sort of the pal park in black and white.
In a way, yes. You can give items to your Pokemon and trade them.
No you cannot only if you trade with someone in Pokemon Black
noyou cant but if you want Pokemon and items use cheats
You can only trade items by attaching an item to a Pokémon and then trading it between Pokémon Black and White games only. You cannot bring items from Pokémon Diamond, Pearl, Platinum, HeartGold or SoulSilver into Black or White.
It's possible, in an indirect way. You have to trade Pokemon from Pokemon Colleseum to Leafgreen, Firered, Ruby, Sapphire, or Emerald, then import to Diamond/Pearl/Platinum, then import to Pokemon Black using the Pokemon Relocater.
You could trade for one.
No, unless you want to trade a Pokemon holding an item that works. But just by item, no it doesn't work like that.
