What are the properties of metals and non-metals?
Answers
Answer:
Metal Physical Properties:
Lustrous (shiny)
Good conductors of heat and electricity
High melting point
High density (heavy for their size)
Malleable (can be hammered)
Ductile (can be drawn into wires)
Usually solid at room temperature(an exception is mercury)
Opaque as a thin sheet (can't see through metals)
Metals are sonorous or make a bell-like sound when struck
Metal Chemical Properties:
Have 1-3 electrons in the outer shell of each metal atom and lose electrons readily
Corrode easily (e.g., damaged by oxidation such as tarnish or rust)
Lose electrons easily
Form oxides that are basic
Fave lower electronegativities
Nonmetal Physical Properties:
Nonmetal Physical Properties:Not lustrous (dull appearance)

Answer:
PROPERTY OF METALS:-
1. Metals are malleable i. e they can be beaten down into thin sheets
2. Metals are ductile i. e. they can be easily drawn into thin wire
3. Metals are hard except sodium and potassium.
4. Metals have lustre.
5. Metals have high melting and boiling point
PROPERTY OF NON-METAL
1.Non-metals are non-mallaeble
2.Non-metals are non-ductile
3.Non-metal are soft
4.Non-metals are not lusture
5.Non-metals have low melting point
