Sample | Conductor of Electricity | Malleability |
I | \[\times \] | |
II | \[\times \] | |
III | \[\times \] | |
IV |
A) I is copper; II is sulphur
B) II is sulphur; III is coal
C) III is iron; IV is copper
D) II is coal; IV is copper
Correct Answer: D
Solution :
Metals show malleability and are good conductors of heat and electricity. While, non-metals are non-malleable but are brittle and bad conductors of heat and electricity. So, II is a non-metal and IV is a metal.You need to login to perform this action.
