WebElements Periodic Table » Sodium » crystal structures

The body-centred cubic (bcc) structure is the most stable form for sodium metal at 298 K (25 C).Under normal conditions, all of the Group 1 (alakali metals) elements are based upon the bcc structure. The closest Na-Na separation is 372 pm implying a sodium

Copper - Wikipedia

Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals).This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposefully alloyed with another

The Three-Dimensional Structure of Bovine Calcium Ion …

2003/7/1· The family of vitamin K-dependent γ-carboxylated calcium binding proteins is important in a variety of tissues and cellular functions. The formation of γ-carboxyglutamic acid (Gla) 1 in the liver derived blood clotting factors, for example, results in calcium-dependent conformational changes in the proteins and functionally important interactions with acidic phospholipid surfaces (1–3).
