ATOMIC SIZE

arrange the following elements according to the increasing atomic size

K, Fr, Li, Na

K- Pótassium

  • Atomic Size: 280pm

Fr- Francium

  • Atomic Size: 348pm

Li- Lithium

  • Atomic Size: 182pm

Na- Sodium

  • Atomic Size: 227pm

[tex]\therefore[/tex]The correct order of increasing by atomic size is Li,Na,K,Fr

Ai, P, Si, Mg

B-Boron

  • Atomic Size: 180pm

Al- Aluminum

  • Atomic Size: 184 pm

P-Phosphorus

  • Atomic Size:195pm

Si- Silicon

  • Atomic Size: 210pm

Mg-Magnesium

  • Atomic Size: 173pm

[tex]\therefore[/tex]The correct order of increasing by atomic size is Mg,B,AI,P,Si
