It is presented a critical consideration of all unusual properties of the scalar a_0(980) and f_0(980)-mesons in the four-quark, two-quark and molecular models. The arguments are adduced that the four-quark model is more preferable. It is discussed the complex of experiments that could finally resolve this issue.

    The measured π+η mass spectrum of Λc+ → n π+ η is best reproduced by chiral-unitary models that include the N(1440) nucleon excitation; the a2(1320) tensor meson does not improve the fit.
