The elements on the left of the periodic table are the , while the elements on the right of the periodic table are the [ non-metals || metals ]
Metals have a tendency to______________, while non-metals have a tendency to ________________.CorrectIncorrect
The picture above shows two metal lattices in a sea of free electrons. The orange metal is sodium, which only loses one electron. The blue metal is magnesium, which loses two electrons.
Of the two metals pictured, the [ orange || blue ] one has stronger electrostatic forces holding it together.
The [ orange || blue ] one would thus be expected to have a higher melting point.
