Question

Modelati structura urmatorilor atomi
Ba: A=137 z=56
Fe:A=5 z=26
He: A=4 z=2
Pb:A=208 z=82
Pt:A=195 z=78
Sn:A=119 z=30
S:A=32 z=16

Answer 1

Ba: A=137 z=56
p=Z=+54
e=Z=-54
n=A-p=137-54=83

Fe:A=56 z=26
p=Z=
e=Z=-26
n=A-p=56-26=30

He: A=4 z=2
p=Z=+2
e=Z=-2
n=A-p=4-2=2

Pb:A=208 z=82
p=Z=+82
e=Z=-82
n=A-p=208-82=126

Pt:A=195 z=78
p=Z=+78
e=Z=-78
n=A-p=195-78=117

Sn:A=119 z=30
p=Z=+30
e=Z=-30
n=A-p=119-30=89

S:A=32 z=16
p=Z=+16
e=Z=-16
n=A-p=32-16=16
