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 ?
An element X with an atomic mass of 60 g/mol has density of 6.23gcm−3. If the edge length of its cubic unit cell is 400 pm, identify the type of cubic unit cell. Calculate the radius of an atom of this element. View Solution A element X with atomic mass 60 g/mol has a de...
(i) Using the dat a in the table, give a reason why it can be estimated that the relative atomic mass of hydrogen is greater than 1.0.T(ii)Calculate the relative atomic mass of hydrogen from these data, giving your answer to four decimal places.(2)(c)(i)Write an equation to ...
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...
