Identify the correct statements from the following. (i) In the periodic table, about 78 % of elements are metals. (ii) In a group, the metallic character decreases from top to battom and in a period the nonmetallic character decreases from left to right. (iii) The element Ho belongs to f -block.

Options

  1. Ai, ii, iii
  2. Bii, iii
  3. Ci, iii
  4. Di, ii

Correct answer

C. i, iii

Step-by-step solution

In the periodic table, about 78% of elements are metals. The element Ho belongs to f-block. The f-block elements are the lanthanides and actinides and are called inner transition elements. 57 La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb70 89Ac, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No102
