Transition metals Flashcards
1
Q
Physical properties
A
- good heat and electricity conductors
- hard and strong
- have high densities
- high melting points(no mercury)
2
Q
Mercury is a…
A
liquid at room temperature so it has a low melting point.

Transition metals compared to alkali metals have…
A
very high melting points
- denser
