what if you send the bitcoin to a legacy wallet non wetsig/lightning will you loose the bitcoin or can the transaction be cancled
You need to be more specific; it's difficult to understand what you mean. You can send your coins to any type of addresses from Electrum. Since Electrum has RBF enabled by default, you can cancel a transaction by replacing it with a transaction paying a higher fee. You can do it easily by right-clicking on an unconfirmed transaction in the "History" tab and selecting "Cancel transaction". Lightning transactions cannot be cancelled since in most cases they are settled in just a few seconds.
