Metallic sodium forms a body centered cubic (BCC) crystal structure with a cube edge length of 4.25 ×10 8 cm . Using this information: Determine the concentration of conduction electrons, assuming each sodium atom contributes one conduction electron.
1
\( n = 2.6 × 10^{22} \, \text{cm}^{-3} \)
2
\( n = 2.6 × 10^{20} \, \text{cm}^{-3} \)
3
\( n = 2.6 × 10^{23} \, \text{cm}^{-3} \)
4
\( n = 2.6 × 10^{19} \, \text{cm}^{-3} \)
