Question

dada as representaçoes a seguir, destaque o numero de massa, prontons, neutrons, atomico e de eletrons: a)23V51 b)25Mn55 c)53I131 d)16S32. depois desenhe o modelo atomico de rutherfordpara as representaçõesdo exercicios anterior.

Answer 1

Resposta:

a)V

1s2,2s2,2p6,3s2,3p6,4s2,3d3

K2,L8,M11, N2.

A=51, Z=23

p=23 n=51-23=28

e=23

b)Mn

1s2,2s2,2p6,3s2,3p6,4s2,3d5.

K2, L8, M13, N2

A=55, Z=25, p=25, n=55-25=30

Z=25. e=25

c)I

Z=53

1s2,2s2,2p6,3s2,3p6,4s2,3d10,4p6,5s2,4d10, 5p5.

K2,L8,M18,N18,O7

A=131 , Z=53. p= 53 n=131-53=78

e= 53

d)S

1s2,2s2,2p6,3s2,3p4

K2, L8, M6

A=32 Z=16 p=16 n= 32-16= 16

e= 16
