%X We present an improved measurement of the carbon-nitrogen-oxygen (CNO) solar neutrino interaction rate at Earth obtained with the complete Borexino Phase-III dataset. The measured rate, RCNO=6.7+2.0−0.8  counts/(day×100  tonnes), allows us to exclude the absence of the CNO signal with about 7σ C.L. The correspondent CNO neutrino flux is 6.6+2.0−0.9×108  cm−2 s−1, taking into account the neutrino flavor conversion. We use the new CNO measurement to evaluate the C and N abundances in the Sun with respect to the H abundance for the first time with solar neutrinos. Our result of NCN=(5.78+1.86−1.00)×10−4 displays a ∼2σ tension with the “low-metallicity” spectroscopic photospheric measurements. Furthermore, our result used together with the 7Be and 8B solar neutrino fluxes, also measured by Borexino, permits us to disfavor at 3.1σ C.L. the “low-metallicity” standard solar model B16-AGSS09met as an alternative to the “high-metallicity” standard solar model B16-GS98.
