Write four difference in the physical properties of metals and nonmetals
Answers
Answer:
Explanation:
Difference between metals and non-metals
The metals are generally present in the solid form at room temperature except mercury which is liquid at room temperature. Whereas non-metals may be solid, liquid and gaseous at room temperature.
Metals are good conductors of heat and electricity but non-metals are poor conductors of heat and electricity.
Metals are ductile in nature i.e. it can be drawn into thin wires. But non-metals are not ductile.
Metals are malleable but non-metals are not malleable. Malleable means the property through which metals can be hammered into thin sheets.
Metals are lustrous i.e. having shinning appearance but non-metals are dull in appearance.
Metals contain 1 to 3 electrons in their outermost shell whereas non-metals contain 4 to 8 electrons in their outermost shell.
Metal loses electrons to form electropositive ions but non-metals accept electrons to form electronegative ions.
