Tabel konfigurasi elektron

Konfigurasi elektron 
Konfigurasi elektron atom gas netral dalam keadaan dasar. Disajikan berdasarkan subkulit dalam bentuk ringkas, dengan subkulit ditulis, dan dengan jumlah elektron per kulit. Konfigurasi elektron setelah unsur nobelium (unsur 102) adalah tentatif dan setelah rutherfordium (unsur 104) adalah prediksi.
