thanks this is very basic and easy for a newbie like me to learn about bitcoins,..
Now that you've seen the trolly pic, you shouldn't do the same mistake as a newbie. You might even send someone your private key instead of your wallet address. You have to do some quick search about the difference of those things. You might as well want to search how to see your wallet address in blockchain. But for someone who has common sense, all of the details in your account in blockchain are self explanatory such as the public key, private key, wallet address, mnemonic code, etc.
