The chemical elements can be divided into metal elements and non-metal ele- ments. Which of the statements about metals and non-metals is correct? A. metals lose electrons to become charged particles called cations B. most of the elements are non-metals. C. non-metals are located at the left hand side of the periodic table D. metals have low melting points and are good conductors of heat
Option A. Metal lose electrons to become charged particles called cations. And nonmetals gain electron to form anion. metal ions are positively charged (having lost an electron/s), con- sequently they are attracted to a cathode (a negatively charged electrode)
