A certain metal M crystallizes in a lattice described by a body-centered cubic (bcc) unit cell. The lattice constant (a, the edge of the unite cell) has been measured by X-ray crystallography to be 360. 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.

radius = 156 pm

Explanation:

The relation between radius and edge length of unit cell of BCC is

r=a/4

Given

a = 360 pm

Therefore

r = r = radius = 360/4= 155.88 pm

Or

156 pm

u i forgot the answer?

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
