Moreover, elements with heavier atomic mass were naturally more decoupled and unpredictable in space than those with lighter mass. Only the coupling of carbon, nitrogen and phosphorus, which are essential to life on Earth, deviated from this predictable pattern, suggesting that this anomaly may be...
An element with atomic mass 93 gmol−1has density 11.5 gcm−3. If the edge length of its unit cell is 300 pm, identify the type of unit cell. View Solution An element crystallises in fcc structure. If the atomic radius is2.2Å, what will be the edge length of the unit cell ?
