Acertain metal crystallizes in a lattice described by a body-centered cubic (bcc) unit cell. the lattice constant a has been measured by x-ray crystallography to be 409pm. calculate the radius of an atom of m. be sure your answer has the correct number of 3 significant digits, and be sure it has the correct unit symbol.

the answer to this question is 3.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
