Answer: The melting point would be lower and the boiling point would be higher

Explanation: From Beryllium to Barium the melting point and the boiling point were constantly decreasing. after that, Radium's boiling point starts to increase in temperature. So I would assume that if there was an element in group 2 with a higher atomic number than Radium it's melting point would continue decreasing while the boiling point increased.
