ስለ Chromium
Chromium is a steely-gray, lustrous, hard metal that takes a high polish. It is remarkable for its resistance to tarnishing. It has an unusual electronic configuration with only one 4s electron due to the stability of a half-filled 3d shell.
ፕሮግራሞች
Stainless steel, chrome plating, pigments, leather tanning, and catalysts.
ሐቅ
Chromium has an anomalous electron configuration -- it 'steals' an electron from 4s to give a half-filled 3d orbital.
