A certain metal M crystallizes in a lattice described by a face-centered cubic (fcc) unit cell. The lattice constant a has been measured by X-ray crystallography to be 526.pm. Calculate the radius of an atom of M. Be sure your answer has the correct number of significant digits, and be sure it has the correct unit symbol.

a is the answer to this question

explanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.

thats not the answer u need to drop the right one bruh
