( Neglijam gluonii , bosonii , quarcii etc...)
Particule subatomice :
- electroni
- protoni
-neutroni
A Zn = 65g/mol
n Zn =1,3/65 = 0,2 moli
In 0,2 moli de Zn se afla
6,022 *10^23 *0,2 =1 ,2044 * 10^23 atomi Zn
1 atom Zn :
- 30 electroni
-30 protoni
-35 neutroni
=> 30*1,2044*10^23=36,132 *10 ^23 electroni / protoni
35*1,2044*10^23=42,154*10^23 neutroni
