Conductivity: very poor
Solubility (H2O): none
Melting point: -157°C Element 2
State of matter: solid
Conductivity: good
Solubility (H2O): reacts rapidly
Melting point: 777°C Element 3
State of matter: solid
Conductivity: poor
Solubility (H2O): none
Melting point: 327°C
Element 4
State of matter: liquid
Conductivity: very poor
Solubility (H2O): negligible
Melting point: -7°C Element 5
State of matter: solid
Conductivity: excellent
Solubility (H2O): none
Melting point: 1085°C Element 6
State of matter: solid
Conductivity: good
Solubility (H2O): reacts violently
Melting point: 29°C
Question
Look back at parts A and B to compare the properties of the unknown elements with the properties of the known elements. Based on these properties, match each unknown element to its group in the periodic table.
