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

  3. SifatPeriodikUnsur • Sifatlogam : cenderungsemakinlemah cenderungsemakinkuat • Jari-jari atom: cenderungsemakinkecil cenderungsemakinbesar • Jari-jari ion positip < jari-jari atomnya. • Jari-jari ion negatip > jari-jari atomnya.

  4. EnergiIonisasi (PotensialIonisasi). Jari-jari atom besar → EI_nya kecil. • AfinitasElektron. Jari-jari atom besar → AE_nya kecil. • Keelektronegatifan. cenderungsemakinbesar cenderungsemakinkecil
