Question

Realizati configuratia electronica a elementelor cu urmatoarele caracteristici:
a. are substratul 3d semiocupat
b. este situat in grupa a 6-a perioada 4
c. este al 5-lea element din blocul p al perioadei 4
d. are 84,322 ori 10 la puterea 23 electroni p intr-un mol de atomi
e. are 175,667 ori 10 la puterea 23 electroni

Answer 1

a - 1s2 2s2 2p6 3s2 3p6 4s2 3d5
b - 1s2 2s2 2p6 3s2 3p6 4s2 3d4 sau 1s2 2s2 2p6 3s2 3p6 4s1 3d5
c - 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5
d 
84,322*10^23/6,022*10^23 = 14 electroni p
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p2
e
175,667*10^23/6,022*10^23 = 29 electroni
1s2 2s2 2p6 3s2 3p6 4s2 3d9 sau 1s2 2s2 2p6 3s2 3p6 4s1 3d10
