The correct decreasing order for metallic character is

Options

  1. ANa > Mg > Be > Si > P
  2. B  P > Si > Be > Mg > Na
  3. CSi > P > Be > Na > Mg
  4. DBe > Na > Mg > Si > P

Correct answer

A. Na > Mg > Be > Si > P

Step-by-step solution

A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires) On moving top to bottom of the periodic table metallic character increases and on moving left to right metallic character decreases. Metallic character is directly proportional to the atomic size. The correct order of atomic size of the given elements is Na
