Minor correction to the very good summary that redceltech gave:

"Users placed in this group assume root level privileges."

should read

"Users placed in this group assume *some* root level privileges."

Being in the root group does not give you all the rights as the root user.
Agreed, nice pick up!

I found this record in the file

username:x:506

what's x and 506 mean,
One other thing to note about the root group. Users with this membership can su or switch user to the root account, that is if they know the password.
506 is the group number. Check the group file and search for 506 (/506 in vi), most likely it is a group created when the user was added. The group number to monitor is 0. x is the password column.
x is shown if shadow passwords are in use
