Question

Determinați pentru fiecare caz protonii, electronii si neutronii la Hidrogen stiind:
Z=6
Determinați:
A) nr de masa = 10
B) nr de masa = 11
C) nr de masa = 12
D) nr de masa = 13
E) nr de masa = 14
F) nr de masa = 15
G) nr de masa = 16

Answer 1

Explicație:

nr de masa = A

protonii=p+

electronii= e-

neutronii=n

a) A=10

Z=6

p+=Z ->p+=6

A=Z+n ->n=A-Z -> n=10-6=4

e-=p+=Z ->e-=6

b)A=11

Z=6

p+=Z ->p+=6

e-=p+=Z ->e-=6

A=Z+n ->n=A-Z -> n=11-6=5

c)A=12

Z=6

p+=Z ->p+=6

e-=p+=Z ->e-=6

A=Z+n ->n=A-Z -> n=12-6=6

d)A=13

Z=6

p+=Z ->p+=6

e-=p+=Z ->e-=6

A=Z+n ->n=A-Z -> n=13-6=7

e)A=14

Z=6

p+=Z ->p+=6

e-=p+=Z ->e-=6

A=Z+n ->n=A-Z -> n=14-6=8

f)A=15

Z=6

p+=Z ->p+=6

e-=p+=Z ->e-=6

A=Z+n ->n=A-Z -> n=15-6=9

g) A=16

Z=6

p+=Z ->p+=6

e-=p+=Z ->e-=6

A=Z+n ->n=A-Z -> n=16-6=10

Sper că te-am putut ajuta! Mult succes!
