Because it has more free electrons, however note that copper is the second best conductor after silver per-unit-volume. Many people think gold is the best conductor but it is not. And maybe also because its a Ionic compound so that its electron can move freely in vecant spaces....so that mobile electrons allow electricty and heat ton pass thru the body. Sorry if i am wrong im just in 8th grade and i am telling what do i know i meant nobody told me anything i have just learned a lil about ionic conpounds n its electrons so its just a hunch..so if i ma wrong then please tell me Thanks^_^
