Understanding the scientific rationale behind Zinc's position in the periodic table:
Belongs to Group 12 because it has 2 valence electrons beyond a filled d-shell (3d¹⁰ 4s²).
Belongs to Period 4 because its outermost electrons occupy n=4.
Belongs to the d-block because the 3d shell completes filling at zinc.
Classified as a transition metal / group 12 metal, though its filled d¹⁰ shell means its chemistry is dominated exclusively by the +2 state.
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: 2.
Mined predominantly from sphalerite (zinc blende / ZnS), smithsonite (ZnCO₃), and hemimorphite.
From German 'Zinke' meaning prong or tooth, referring to its spiky crystal formations
Inhaling freshly formed zinc oxide fumes from welding galvanized steel causes 'metal fume fever' (zinc shakes).
