Eriq, a chemist, is running tests with four unknown elements. He has found that they all bond the same way, so he knows that they are in the same group on the periodic table of elements. The table shows other properties that Eriq observed.
\multicolumn{4}{|c|}{Properties of Four Unknown Elements}
Element \#Melting point Boiling point Phase at room temperature
1266 K 332 K liquid
2172 K 239 K gas
3387 K 457 K solid
453 K 85 K gas
These four elements are most likely in group
A15.
