What are characteristics of nonmetals?

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 3

1.They are poor conductors of heat & electricity.

2.They are dull.

3.They are found in all 3 states of matter solids liquids & gas.

4.They have low melting & boiling points.

5.They can not be drawn into wires or beaten into foil & plates.

Carbon.Oxygen.

Iodine & sulphur are some examples of non metals.
