The metallurgical process in which a metal is obtained in a fused state is called__________?
Correct answer: A. smelting
- A. smelting
- B. roasting
- C. calcinations
- D. froth floatation
Explanation
Smelting is the metallurgical process in which a metal or its compound is heated strongly, often with a reducing agent, to produce the metal in a molten or fused state. Roasting uses excess oxygen, calcination uses limited or no air, and froth flotation concentrates ore, so option a is correct. Students may choose roasting because it also involves strong heating, but roasting does not itself mean obtaining the fused metal.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
