Yes, there is a chance
when u deactivate your account when your friends open their friends list it will show your name with empty profile.

if they don't check the list there is no possibility of knowing it..!

[Angeleyes]

Yes, people will know you activated your account as your profile pic will be gray and also your friends will see that. They cannot contact you anymore, if they try to send you a message it will say this account has been deactivated.

Yes, everyone lost a friend and you have completely disappeared from the database.
