Q19 / 90 · JEE Main 2023 (25 Jan Shift 2) · Chemistry

Which of the following represents the correct order of metallic character of the given elements?

  • Correct answer
    A
    Si<Be<Mg<K
  • B
    Be<Si<Mg<K
  • C
    K<Mg<Be<Si
  • D
    Be<Si<K<Mg

Solution

Group 1 elements are most metallic, as we go across the periodic table metallic character increases while going down the group and decreases along the period. Silicon is p-block element, potassium, beryllium and magnesium are s-block elements.

Hence, the correct answer is option: 'A'.
