Which of the substances from the list below would be considered examples of metallic solids?
S8
Sn
SiO2
Na2SO4
Ga
As2O3
K2Cr2O7
Se
Homework Answers
Ionic solid consist of metal and nonmetal in it. like Na+ is metal having positive charge and SO42- nonmetal having negative charge. and K2Cr2O7 also.Ionic solids also have high melting points.
Molecular solids generally made of nonmetals and having low melting points eg.S8
Metallic can conduct electricity very well , ductile mellable and as given in question it should be solid aslo so i think Sn is the answer , which satisfy all the properties. Ga is also but it is liquid above 30Celcius.
Se and SiO2 are network covalent solids.
As2o3 is molecular solid
