Understanding the scientific rationale behind Germanium's position in the periodic table:
Belongs to Group 14 because it has 4 valence electrons (4s² 4p²).
Belongs to Period 4 because its outermost electrons occupy n=4.
Belongs to the p-block because its valence electrons occupy 4p orbitals.
Classified as a metalloid due to its semiconductor bandgap (0.66 eV) and diamond cubic crystal lattice.
Hover or tap any shell orbit ring to inspect electron counts and 2n² capacities.
Educational Note: This Niels Bohr planetary model visually illustrates principal quantum energy shells ($n=1, 2, 3\dots$) and electron counts. In modern quantum mechanics (Schrödinger model), electrons do not orbit in fixed circular planetary tracks, but exist as 3D probability clouds (orbitals: $s, p, d, f$) governed by the Heisenberg uncertainty principle.
Neutral ground state configuration. Valence electrons: 4.
Extracted from sphalerite zinc ores, argyrodite, and certain coal fly ash deposits.
From Latin 'Germania' meaning Germany
Elemental germanium is relatively non-toxic; germane gas (GeH₄) is extremely toxic and flammable.
