Question

reprezentau modelul de formare a ionilor, pt. : z=20 ; z=19 ; z=13

Answer 1

pt: Z= 20:
$1s^2 2s^22p^63s^23p^6 4s^2$ = $-2e^-$=> $Ca ^{2+} :1s^2 2s^22p^63s^23p^6$

Z=19 : 
$1s^2 2s^22p^63s^23p^6 4s^1$ =$-1e^-$=> $K^{1+}: 1s^2 2s^22p^63s^23p^6$

Z=13:
$1s^2 2s^22p^63s^23p^1$ =$-3e^-$=> $Al^{3+}: 1s^2 2s^22p^6$
