A certain metal M crystallizes in a lattice described by a face-centered cubic (fcc) unit cell. The radius r of M atoms has been measured to be 179.pm. Calculate the lattice constant a of a crystal of M. Be sure your answer has the correct number of significant digits, and be sure it has the correct unit symbol.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
