open electrum and do one of these things:
1) if you want only one Private key:
go to addresses tab and right click on the bitcoin address you want and select "Private key" enter your wallet password and you will see the address's private key. you can copy now
2) for all of them:
in the toolbar click on Wallet > Private keys > export
you may need your wallet password.
wait for the list to build then you can see all of them you can either copy one by one or export it to a file using CSV or JSON format
