Answers
ok hope it helps you
1a giving out or capable of giving out a sound, especially a deep, resonant sound, as a thing or place: a sonorous
1b Silver and Copper are said to be most sonorous metals
2 Non-Metals can be solids, liquids and gases
They can be soft
They are dull
They are not malleable
They are not ductile
They are bad conductors of heat and electricity
Low melting points and low boiling points ( if liquid )
Every day Metals
Aluminum ( kitchen utencils )
Copper ( electrical wire )
Gold ( jewellery
Every day Non Metals
Clorine ( kills germs in water )
Sulfur ( to make match stick heads)
Diamond ( jewelery and for cutting marble)
What is a Metal?
Metals are found inside of rocks and they have ti mined out of their ore, with a process called smelting.
Properties of Metals
Solid at room temperature ( except mercury )
Shiny
Good conductor of heat and electricity ( silver and copper)
Malleable
Ductile
They are sonorus
They have high melting points
They have high boiling points
3 he transition elements are both ductile and malleable, and conduct electricity and heat. They are generally hard and dense, and less reactive than the alkali metals. Iron, copper, silver and gold are important transition metals.
