How do you handle a kid who is violent in nature? That is scratched and beat you suddenly. Have held her hands and talk to her many x but nothing seems to work

Ask her to imagine how she would feel if the tables were turned and she was at the receiving end of being scratched and beaten. She should treat others the way she wants to be treated. If all else fails, put her on a timeout or take away her privileges if she continues. For example, if she gets to watch TV at night, tell her she cannot if she continues her "violent" ways.
