Metals and Non-metals
Metals and Non-metals
Metals are elements that have a tendency to lose electrons and form positively charged ions or cations.
Elements that have a tendency to accept electrons to form negatively charged ions or anions are called non-metals.
Metals are placed on the extreme left in the periodic table, while non-metals are placed on the extreme right in the periodic table.
Metals are solids, malleable, ductile, lustrous with high milting and boiling points.
Metals are electropositive, good conductors of heat and electricity, form basic oxides which are ionic.
Non-metals exist as solids, liquids and gases, non malleable, non ductile, non-lustrous with low melting and boiling points.
Non-metals are electronegative, bad conductors of heat and electricity, form acidic oxides which are covalent.
Electrolysis is a process of decomposition of an ionic compound by passing electricity through it.
