What are the three general characteristics of nonmetals?

Answer 1

The 3 characteristics of a nonmetal's is that they don't conduct heat very well, they are very hard and brittle, can be solids liquids and gasses at room temp where as metals are always solid apart from Mercury and they don't conduct electricity, there is 1 exception which is carbon which does conduct electricity but is a metal.

Answer 2

non metals are brittle they tend not to conduct electricity (exception is silicon) they tend not to conduct heat they tend to form anions they often are gases, but can be solid or even liquid (bromine) at STP

Answer 3

Summary of Common Properties

• High ionization energies
• High electronegativities
• Poor thermal conductors
• Poor electrical conductors
• Brittle solids
• Little or no metallic luster
• Gain electrons easily

Answer 4

1. Nonmetals are poor conductors of heat and electricity.
2. They tend to gain electrons in chemical reactions.
3. Nonmetals are typically brittle in solid form and have lower melting and boiling points compared to metals.

Answer 5

1) React with oxygen to form acidic oxides

2) Poor conductors of electricity and heat

3) The ions are negative, except hydrogen that forms a positive ion (H+).

Answer 6

There are three characteristics of most nonmetals. They are more malleable and ductile than metals, they have ionization energies, and thy are poor conductors.

Answer 7

1. They are not metal.

2. In liquid or gas, the particles can move a lot more than in a solid metal.

3. Usually non metals are more malleable and ductile.

Answer 8

- not lustrous (no shine)

- brittle (breaks easily)

- not malleable

Answer 9

They have luster, are good conductors of heat and electricity, are ductile and malleable.
