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 \( \mathrm{X} \)-ray crystallography to be \( 365 . \mathrm{pm} \). Calculate the radius of an atom of \( M \). Be sure your answer has 3 significant digits, and be sure it has the correct unit symbol.
