Question

Write physical properties of metals and non metals

Answer 1

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

Are good reducing agents

Nonmetals

Nonmetals, with the exception of hydrogen, are located on the right side of the periodic table. Elements that are nonmetals are hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, all of the halogens, and the noble gases.

Nonmetal Physical Properties:

Not lustrous (dull appearance)

Poor conductors of heat and electricity

Nonductile solids

Brittle solids

May be solids, liquids or gases at room temperature

Transparent as a thin sheet

Nonmetals are not sonorous

Nonmetal Chemical Properties:

Usually have 4-8 electrons in their outer shell

Readily gain or share valence electrons

Form oxides that are acidic

Have higher electronegativities

Are good oxidizing agents

Both metals and nonmetals take different forms (allotropes), which have different appearances and properties from each other. For example, graphite and diamond are two allotropes of the nonmetal carbon, while ferrite and austenite are two allotropes of iron. While nonmetals may have an allotrope that appears metallic, all of the allotropes of metals look like what we think of as a metal (lustrous, shiny).

Answer 2

Answer:

HERE IS YOUR ANSWER MATE:-

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)

Properties Of Nonmetals:-

➡Form Covalent/Ionic Bonds.

➡One of the primary characteristics of nonmetals is that they form chemical compounds by making covalent and ionic bonds.

➡Brittle.

➡Low Melting/Boiling Points.

➡High Ionization Energy/Electronegativity.

➡Poor Conductors Of Heat And Electricity.
