A metal crystallizes in a face-centered lattice. The radius of the atom is 198pm and the density of the element is 6.57g/cm^3. What is the identify of the metal?

  • Chemistry -

    4r = a(2)^1/2
    solve for a.

    Then volume = a^3

    mass = volume x density. Solve for mass.
    mass = 4*atomic mass/6.02E23
    Solve for atomic mass.
