AP EAMCET · Chemistry · Classification of Elements and Periodicity in Properties
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.
- A i, ii, iii
- B ii, iii
- C i, iii
- D i, ii
Answer & Solution
Correct Answer
(C) i, iii
Step-by-step Solution
Detailed explanation
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,…
