Tolong bantu jawab:
1. A. Proton=24,
neutron= 54-24=30,
elektron=24-2=22
B. Proton = 18
neutron = 40-18 = 22
elektron = 18
C. Proton = 83
neutron = 209-83 = 126
elektron = 83+3=86
D. Proton = 37
neutron = 85-37=48
elektron = 37
E. Proton = 35
neutron = 80-35=45
elektron = 35+1=36
F. Proton = 27
neutron = 58-27 = 31
elektron = 27-2 = 25
2. A. 16O8 dan 15O8
B. 85K37 dan 20Ne10
C. 13C6 dan 13N7
maaf kalo salah
