Which type of drugs kill pain by blocking impulses at specific receptor sites of the brain and spinal cord? narcotic analgesics non-narcotic analgesics anti-psychotics tranquilizers

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
