Question

Physical properties of metals​

Answer 1

Answer:

Physical properties are the characteristics of matter that can be observed and measured without any change to the chemical identity of the sample. A physical property measurement might change the arrangement of matter in a sample but not the structure of its molecules.

Explanation:

I think this is right

Answer 2

Answer:

Physical properties of metals​

Explanation:

Metals and non-metals have different properties and different reactions. These differences in reactivity depend on where an element is placed in the periodic table.

Shiny Dull  

High melting points Low melting points

Good conductors of electricity Poor conductors of electricity

Good conductors of heat Poor conductors of heat

High density Low density

Malleable and ductile

Some elements have properties that are not typical. For example:

mercury (a metal) has a low melting point and exists as a liquid at room temperature

graphite, a form of carbon (a non-metal), has a high boiling point and is also a good conductor of electricity

A substance with a high density means it has a high mass for its size.

Malleable substances can be bent or hammered into shape without shattering, while brittle substances shatter when bent or hit.

Ductile means that a substance can be drawn out into a long wire without snapping or breaking.
