Solution: The melting points of metals from periods 4, 5, and 6.Which element in sixth period has the highest melting point?

Problem

The x axis is groups 1A to 2B and y axis is melting point (kelvin) 0 to 4000. Three lines are plotted, one each for periods 4 to 6.  Melting point for group 1A periods 4, 5 and 6 is 300 degrees.  Melting pt for group 2A periods 4, 5 and 6 is 1100 degrees.  Group 3B periods 4 and 5 melt at 1800, period 6 melts at 1900. Group 4B period 4 melts at 2000 degrees, period 5 at 2100 and period 6 at 2500. Group 5B period 4 melts at 2200 degrees, period 5 at 2700 and period 6 at 3300. Group 6B period 4 melts at 2200, period 5 at 2900 and period 6 at 3600.  Group 7B period 4 melts at 1500, period 5 at 2500 and period 6 at 3500.  Group 8B period 4 melts at 1800, period 5 at 2600, and period 6 at 3300.  Group 8B period 4 melts at 1700, period 5 at 2300, and period 6 at 2700.  Group 8B period 4 melts at 1600, period 5 at 1800, and period 6 at 2000. Group 1B period 4 5, and 6 melts at 1400. Group 2B period 4 and 5 melts at 700 and period 6 at 2500.
