We have studied the dynamics of atom motion at metal (100) surfaces. The interactions between atoms are modelled with central forces and angle bending forces. Results for frequencies and polarizations of surface modes have been obtained for the following metals : body centered Cr, Fe, K, Mo, Na, V, W ; face centered Ag, Al, Au, Cu, Ir, Ni, Pd, Pt, Rh. Specific results are presented for Cr and Ni.
