Question

which property of metal make them suitable for use in jewellery ​

Answer 1

The properties of metals which make them suitable for their use in jewellery are as follows:

• Shiny (lustrous)

• Malleable

• Ductile

Shine of metals :

• Metals shine due to presence of free electrons on the surface. This metallic lusture helps to make the jewellery more attractive.

Malleable character:

• Metals can be beaten into thin sheets. Thin sheets can be used to produce various components of a jewellery.

• Malleable character of metals like gold and silver helps us to create gold and silver coins.

Ductility:

• Ductility refers to the ability of being drawn into a wire. This character of metals helps to create gold wires which can hold the other components of the jewellery

Hope It Helps.

Answer 2

Ans=  

metals are substance  or minerals  which form  under the earth surface

which have special properties like

1. meliability
2. ductility
3. sonours

• if metals are react  with water it gives heat . e.g sodium
• if metals are react with acid it gives  hydrogen gas
• if metals are react with oxygen it gives metal oxides
• metals are good conductor of heat

by observing  this property we use metals in making jewellery

becoz of metals are shiny, durable and ductile
