Catalysis of the transmembrane transfer of an ion by a channel that opens when a specific extracellular ligand has been bound by the channel complex or one of its constituent parts. Catalysis of the energy-independent passage of cations across a lipid bilayer down a concentration gradient. null Catalysis of the transfer of metal ions from one side of a membrane to the other. Catalysis of facilitated diffusion of an ion (by an energy-independent process) by passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism. null
