Question

Kimia atom kelas 10, nomor atom dan masa, minta tolong

Answer 1

Penjelasan:

1. Proton = 3

Neutron = 7-3 = 4

Elektron = 3-1 = 2

2. Proton = 8

Neutron = 16 - 8 = 8

Elektron = 8 - (-2) = 10

3. Proton = 11

Neutron = 23 - 11 = 12

Elektron = 11 - 1 = 10

4. Proton = 20

Neutron = 40 - 20 = 20

Elektron = 20 - 2 = 18

5. Proton = 25

Neutron = 80 - 25 = 55

Elektron = 25 - (-1) = 26
