kak tolong bantu kerjain kalau benar aku follow sm kasih 8 poin
makaseh​

Answer 1

Jawaban:

He = Helium

proton = 2

neutron = 2

Fe = Ferrum/besi

nomor atom = 26

nomor massa = 56

Al = Aluminum

proton = 13

elektron = 13

Ca = Calsium / Kalsium

proton = 20

neutron = 20

elektron = 20

C = carbon / karbon

proton = 6

elektron = 6

neutron = 8

F = Flouride/Fluor

nomor atom = 9

nomor masaa = 19

elekyron = 9

H = hydrogen/hidrogen

nomor atom = 1

elektron = 1

neutron = 0

H= hidrogen

proton = 1

elektron = 1

neutron = 1

Penjelasan:

Nomor massa selalu lebih besar dari nomor atom.

Nomor Atom = jumlah elektron

Jumlah Elekktron = Jumlah Proton

Jumlah neutron

= nomor massa - nomor atom
