SIFAT PERIODIK UNSUR

tabel periodik bentuk panjang
Tabel Periodik bentuk Panjang
  • Baris = periode (= kulit) : 1 sd 7
    • Periodependek : 1, 2, 3
    • Periodepanjang : 4, 5, 6, 7
  • Kolom = golongan.
    • Utama (A) : IA sd VIIIA
    • Transisi (B) : IB sd VIIIB
      • Luar

  • Unsurblok s → berakhir orbital s.
  • Unsurblok p → berakhir orbital p.
  • Unsurblok d → berakhir orbital d.
  • Unsurblok f → berakhir orbital f.
