Which of the first 20 elements in the periodic table are metal and which are nonmetals?What property of nonmetallic elements makes more likely to gain electrons than lose electrons?Suppose element X is a poor conductor of electricity and...
“Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity...
