1. Reaksi dengan air Mangan bereaksi dengan air dapat berubah menjadi basa secara perlahan dan gas hidrogen akan dibebaskan sesuai reaksi: Mn(s) + 2H2O → Mn(OH)2 +H2

2. Reaksi dengan udara Logam mangan terbakar di udara sesuai dengan reaksi: 3Mn(s) + 2O2 → Mn3O4(s) 3Mn(s) + N2 → Mn3N2(s)

3. Reaksi dengan halogen Mangan bereaksi dengan halogen membentuk mangan (II) halida, reaksi: Mn(s) +Cl2 → MnCl2 Mn(s) + Br2 → MnBr2 Mn(s) + I2 → MnI2 Mn(s) + F2 → MnF2 Selain bereaksi dengan flourin membentuk mangan (II) flourida, juga menghasilkan mangan (III) flourida sesuai reaksi: 2Mn(s) + 3F2 → 2MnF3(s)

4. Reaksi dengan asam Logam mangan bereaksi dengan asam-asam encer secara cepat menghasilkan gas hidrogen sesuai reaksi: Mn(s) + H2SO4 → Mn2+(aq) + SO42-(aq) + H2(g)
