Neutrino scattering on atomic systems at low-energy transfer is a powerful tool for searching the neutrino electromagnetic interactions [1,2]. The regime of coherent elastic neutrino-atom scattering (CEνAS), i.e., when the atom recoils as a pointlike particle, can be effectively fulfilled in the case of tritium neutrinos [3]. We present theoretical calculations for CEνAS processes on such targets as the H, $^2$H, $^3$He, $^4$He, and $^6$C atoms. We show how the atomic effects and neutrino electromagnetic properties, namely the neutrino millicharge and magnetic moment, may manifest themselves in the atomic-recoil spectra. Our results can be used in planning the CEνAS experiments (in particular, with superfluid $^4$He [3,4]).
