Metals and ironMetals Metals Metals are elements that conduct heat and electricity and are malleable and ductile . • All metals → Solid (except mercury) • Metals are electropositive . • Metals are the elements (except hydrogen) which form +ve ions by losing electrons . • Most abundant metal in Earth 's crust is Al . WonMetals They do not condat heat and electricity and are neither malleable nor ductile . • Out of 22 non -metals , 90 are solids , 9 (bromine) is a liquid whereas remaining 99 are gases. • Nonmetals are electronegative . • H is only nonmetal which loses electron .
