Which of the following is NOT a property of the transition metals?
0%
Hard
0%
Malleable
0%
Good thermal conductor
100%

Q.8.
One alloy made from a transition element is bronze, produced from copper and tin. Bronze was used in the manufacture of swords. They were found to be much harder than swords made of pure copper or tin. Why are bronze swords harder than copper swords?
0%
In the pure element, the atoms are arranged in sheets where they can slide over each other. With bronze, the tin atoms prevent this from happening
100%
In the pure element, the atoms are arranged haphazardly and are hard to move
0%
In the pure element, the atoms are not able to move at all, but in the alloy, the atoms can move around
0%
The tin atoms in the alloy allow the copper atoms to move freely making the alloy really strong

Mercury
0%
Gold
