Question

ion mas estable del argon

Answer 1

ion mas estable del argon

Z = 18 (Ar)

Configuración electrónica del cloro

Z = 17

Cl (17) =1s²  2 s²  2p⁶  3s²    3p⁵

Cl⁻ (18 e⁻) = 1s²  2 s²  2p⁶  3s²    3p⁶  (gana un electrón)

Cl⁺ (16 e⁻) = 1s²  2 s²  2p⁶  3s²    3p⁴

el ion Cloruro (Cl⁻)  (anión monovalente) = es la más estable Gas Noble (Ar): ns²  p⁶

              Cl⁻ (18 e⁻) = 1s²  2 s²  2p⁶  3s²

Z = 20 (Ca)

Ca (2O e⁻) = 1s²  2 s²  2p⁶  3s²  3p⁶ 4s² (pierde 2 e⁻)

Ca⁺2 (18 e⁻) = 1s²  2 s²  2p⁶  3s²  3p⁶

Catión divalente más estable (Ca⁺²)

forman el CaCl2 =  (Ca⁺2  Cl⁻)
