Options

  1. A2
  2. B3
  3. C6
  4. D8

Correct answer

C. 6

Step-by-step solution

Sodium (+1), scandium (+3) and fluorine ((-1) ) show only one non-zero oxidation state. The oxidation states of oxygen are (-1,-2 ) and +2 The oxidation states of chlorine range from -1 to +7. The oxidation states of nitrogen and phosphorus range from -3 to +5. The oxidation states of tin range from +2 to +4. The oxidation states of scandium is +3. Scandium ((Z=21) ) does not exhibit variable oxidation states and yet it is regarded as a transition element because scandium has partially filled (d )-orbitals in the g
