Oblicz,ile neutronów mają izotopy argonu:
36 Ar
18
38 Ar
40 Ar
n = 36 - 18 = 18
n = 38-18 = 20
n = 40-18 = 22
Pozdrawiam ;)
a) Z=18------> l.p+ =18 , l.e- = 18
A= 36----->l.n0= A - Z= 36-18=18
b)Z=18------>l.p+ =18, l.e- = 18
A=38------>l.n0 = A-Z= 38-18= 20
c)Z=18-------> l.p+ =18, l.e- = 18
A=40--------> l.n0 = A-Z= 40-18= 22
Proszę;**
Na 100% jest dobrze^^
