Pure nickel is___________________?
Correct answer: D. Ferromagnetic at room temperature
- A. Ferromagnetic above its curie point (i.e., 415°C)
- B. Having h.c.p. crystal lattice
- C. Not resistant to oxidation at high temperature
- D. Ferromagnetic at room temperature
Explanation
Nickel is ferromagnetic at room temperature and loses ferromagnetism above its Curie temperature of approximately 358°C, not 415°C. Its crystal structure is face-centred cubic rather than hexagonal close-packed.
