Question

RAPIDDDD, VA ROGG
Al(Z=13) Cl (Z=17) O (Z=8)
se cere
configuratia electronica locul in SP, caracter chimic si electrochimic, valentsla
formarea ionilor

Answer 1

Al, Z = 13

configuratia electronica

1s2 2s2 2p6 3s2 3p1

locul in SP

gr = 3 (III-A), per = 3

caracter chimic metalic si electrochimic electropozitiv

valenta 3

formarea ionilor

1s2 2s2 2p6 3s2 3p1 _-3e-_> 1s2 2s2 2p6 Al(3+)

Cl, Z = 17

configuratia electronica

1s2 2s2 2p6 3s2 3p5

locul in SP

gr = 7 (VII-A), per = 3

caracter chimic nemetalic si electrochimic electronegativ

valenta 1

formarea ionilor

1s2 2s2 2p6 3s2 3p5 _+1e-_> 1s2 2s2 2p6 3s2 3p6 Cl(-)

O, Z = 8

configuratia electronica

1s2 2s2 2p4

locul in SP

gr = 6 (VI-A), per = 2

caracter chimic nemetalic si electrochimic electronegativ

valenta 2

formarea ionilor

1s2 2s2 2p4 _+2e-_> 1s2 2s2 2p6 O(2-)
