MCQ
In the periodic table, metallic character of the elements shows one of the following trend
  • A
    Decreases down the group and increases across the period
  • B
    Increases down the group and decreases across the period
  • ✓
    Increases across the period and also down the group
  • D
    Decreases across the period and also down the group
✓

Answer

Correct option: C.
Increases across the period and also down the group
c
When we are moving from left to right in a periodic table acidic character of oxides increases (as well as atomic number of atom increases)

$X < Y < Z$

$X < Y < Z \quad \text { (atomic number) }$
