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 1495 °C. The melting point of substance B is 98 °C.Predict which substance, A or B, is the transition metal.
Solution
Transition metals generally have higher melting points compared to alkali metals. This is due to the stronger metallic bonding in transition metals, which is a result of their multiple valence electrons.
Substance A has a melting point of 1495 °C, which is significantly higher than the melting point of substance B, which is 98 °C.
Therefore, based on the given melting points, it can be predicted that substance A is the transition metal and substance B is the alkali metal.
