The melting point of two unknown substances are compared. One of the substances is thought to be an alkali metal and the other is a transition metal.The melting point of substance A is 63.5 °C. The melting point of substance B is 1910 °C.Predict which substance, A or B, is the transition metal.
Question
The melting point of two unknown substances are compared. One of the substances is thought to be an alkali metal and the other is a transition metal.The melting point of substance A is 63.5 °C. The melting point of substance B is 1910 °C.Predict which substance, A or B, is the transition metal.
Solution
Transition metals generally have higher melting points than alkali metals. This is due to the stronger metallic bonding in transition metals, caused by the delocalization of more electrons.
In this case, substance A has a melting point of 63.5 °C and substance B has a melting point of 1910 °C.
Given the information, we can predict that substance B, with the higher melting point, is likely the transition metal.
