Chemistry uses of metals M8 Y10

What is a metal

A metal in chemistry is defined as an element that can easily form positive ions called cations and tends to participate in metallic bonding.

What does it mean to be malleable

If something is malleable, it means it can be hammered or pressed into shape easily, without breaking or cracking.

What does it mean to be ductile

They are able to be drawn out easily into a thin wire.

What does it mean by good conductors of electricity

Most metals are great conductors of electricity because they have delocalised electrons. The best conductors of electricity are copper, silver, and gold. 

What does it mean by metals forming ionic compounds

An ionic compound is a chemical compound composed of ions held together by electrostatic forces.

What are the properties of metals

• Malleable

• Ductile

• Good conductors of heat

• Good conductors of electricity

• They form ionic compounds

What does it mean by non-metals having low melting and boiling points?

Non-metals have much lower melting and boiling points compared to metals. This means that at room temperature, a lot of non-metals are either liquids or gases. The reason for this is that non-metals are held together by weak inter-atomic forces of attraction that can be broken easily by heat

What does it mean by non-metals forming ionic and covalent compounds

An ionic compound consists of a metal and a non-metal bonded together. However, non-metals can also bond together with other non-metals to form covalent compounds. 

What happens when a metal forms an oxide

Metals form basic oxides
Basic oxides react with acids to form salts.

What happens when non-metals react with oxides

Non metals form acidic oxides

What are neutral oxides

• Some oxides do not react with either acids or bases and thus are said to be neutral

• Examples include N2O, NO and CO

What are amphoteric oxides?

• Amphoteric oxides are a curious group of oxides that can behave as both acidic and basic, depending on whether the other reactant is an acid or a base

• zinc oxide and aluminum oxide

What are metals grouped as?

• Alkali metals

• Alkali earth metals

• Transition metals

• Rare earth metals

• Heavy metals

Where are metals used

• In the construction Industry

• In electronics

• In medicine

• Machinery, refractory and automobiles

• Decorative products
