Characteristics of a non metal

Answer 1

Characteristics of nonmetals include:

• Rarely have metallic luster (shine)
• Generally gases at room temperature
• Neither malleable nor ductile
• Brittle and dull
• Insulator--Poor conductors of heat and electricity; absorbs heat
• Usually exist as molecules in their elemental form
• Combine with other nonmetals to form covalent
• Generally form negative ions, e.g. Cl-, SO42-, and N3-
• High electronegativity
• High ionization energy
• Small atom size
• Gain electrons to complete their octet
• Low boiling and heating points
• Mostly in liquid or gas form
• Located at the top right of Periodic Table
• Good oxidizing agents; form acidic oxides

Answer 2

They rarely have metallic luster (sunshine)

They are brittle and dull

They are poor conductors of heat and electricity

They have generally lower densities than metals

They are sometimes gases

They have greater electronegativities

They have lower melting and boiling points

etc.

Answer 3

Some characteristics of non-metals are that they are poor conductors of electricity and heat, brittle, and have high electronegativities. On the periodic table, examples of non-metals are nitrogen, carbon, the halogens, and sulfur.

Answer 4

Physical Properties

• Non metals have low melting and boiling points ( Exceptions : those non metals with macromolecular structures - carbon , silicon , boron , germanium ).
• They are bad conductors of heat and electricity ( Exception : Graphite ).
• They are soft ( Exceptions : those non metals with macromolecular structure - carbon , silicon , boron , germanium ).
• They have low densities .
• Brittle ( don't shape but break ) ; ( Exception : Graphite ).
• Not sonorous ( think of a bell ).
• Have a dull surface ( Exceptions : Graphite and iodine ).

Chemical Properties :-

• 4 , 5 , 6 or 7 valency electrons .
• Either gain or lose electrons to form anions ( negative ions ) or share electron pairs .
• Form covalent compounds with other non metals .
• Non metal oxides are usually acidic ; few are neutral .
• Do not react with acids to give a salt and hydrogen .

Answer 5

They are much easier to Bend, for starters. The Avatar doesn't have to work as hard to master the non-metal ones.
