We calculate the CP-averaged branching ratios and CP-violating asymmetries of a number of two-body charmless hadronic decays B{sub s}{sup 0}{yields}PP, PV, VV in the perturbative QCD (pQCD) approach to leading order in {alpha}{sub s} (here P and V denote light pseudoscalar and vector mesons, respectively). The mixing-induced CP violation parameters are also calculated for these decays. We also predict the polarization fractions of B{sub s}{yields}VV decays and find that the transverse polarizations are enhanced in some penguin-dominated decays such as B{sub s}{sup 0}{yields}K*K*, K*{rho}. Some of the predictions worked out here can already be confronted with the recently available data from the CDF Collaboration on the branching ratios for the decays B{sub s}{sup 0}{yields}K{sup +}{pi}{sup -}, B{sub s}{sup 0}{yields}K{sup +}K{sup -} and the CP asymmetry in the decay B{sub s}{sup 0}{yields}K{sup +}{pi}{sup -}, and are found to be in agreement within the current errors. A large number of predictions for the branching ratios, CP asymmetries, and vector-meson polarizations in B{sub s}{sup 0} decays, presented in this paper and compared with the already existing results in other theoretical frameworks, will be put to stringent experimental tests in forthcoming experiments at Fermilab, CERN LHC, and Super B factories.
