(i) Ar, Cl- , K+ , S2-, Ca2+
(ii) Fe, Fe2+, Fe+
(iii) Na, Rb, K

Respuesta :

Just Note the below follow the below principle

[tex]\boxed{\sf SCLA}[/tex]

  • It stands for Smaller cation and larger anion.

#1

[tex]\\ \sf\longmapsto Ar<Ca^{2+}<K^+Cl^-<S^{2-}[/tex]

#2

[tex]\\ \sf\longmapsto Fe^{2+}<Fe^+<Fe[/tex]

#3

[tex]\\ \sf\longmapsto Na<K<Rb[/tex]

#4

[tex]\\ \sf\longmapsto B<C<N<O<F[/tex]
