The metals in Group 1, such as lithium ... dark grey solid and is brittle (non-metallic properties) but has a high melting point and is a conductor of electricity and heat (metallic properties).
The table shows the melting point and density of iron, compared to three non-transition metals. Iron, a transition metal, has a higher melting point and a higher density than the non-transition ...
Refractory metals are a class of metals that are extraordinarily resistant to heat and wear and have extremely high melting points. Reactive metals have a strong affinity for oxygen and nitrogen at ...
1 It appears that this is taken by them to be the true melting point of nitrobenzene of really high purity.
