What are the properties of metals and non-metals?​

Answer»

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)

Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricity

Nonmetal Physical Properties:Not lustrous (dull appearance)Poor conductors of heat and electricityNonductile solids
