Tabel afinitas elektron
Afinitas elektron adalah energi yang dilepaskan ketika atom netral dalam wujud gas menangkap satu elektron membentuk ion negatif, dalam elektronvolt (eV). Nilai yang lebih besar berarti atom memegang elektron tambahan itu lebih kuat.

RendahTinggi(eV)
Tidak ada dataTrennya
Afinitas elektron umumnya naik sepanjang periode menuju halogen, yang memiliki nilai tertinggi. Nilai terbesar dimiliki klor, bukan fluor: fluor sangat kecil sehingga elektron yang ditambahkan berdesakan dengan elektron yang sudah ada. Gas mulia dan beberapa unsur lain tidak membentuk ion negatif yang stabil, sehingga tidak memiliki nilai di sini.
Tertinggi
- Klorin (Cl)3,62 eV
- Bromin (Br)3,37 eV
- Fluorin (F)3,34 eV
- Iodin (I)3,06 eV
- Astatin (At)2,8 eV
Terendah
- Titanium (Ti)0,08 eV
- Renium (Re)0,15 eV
- Besi (Fe)0,16 eV
- Skandium (Sc)0,19 eV
- Talium (Tl)0,2 eV
