Question

property of metals

and distinguish between metals and nonmetals​

Answer 1

Answer:

Three properties of metals are: Luster: Metals are shiny when cut, scratched, or polished. Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped.

Non-metals are bad conductors of heat and electricity. Except for graphite which is a good conduction of electricity. Metals are lustrous and can be polished. Metals are solids at room temperature.

02 Acid, Bases and Salt.

Metals

Metals form basic oxides.

Non-Metals

Non-metals form acidic oxides or neutral oxides

Answer 2

A metal is a material that has a glossy appearance when freshly produced, polished, or shattered, and conducts electricity and heat reasonably well.

Explanation:

Metal has the following properties:

• Melting point: To melt or boil a thing, energy is delivered to it. This energy is required to counteract the forces of attraction that exist between the metal ions and the metal's delocalized electrons. The greater the melting or boiling point, the more energy is required.
• Malleability and ductility: Metals have layers of metal ions that make up their structure. When a force is given to these layers, they can glide over each other. This means that the metal layers can be pounded flat and stacked on top of one another to form thin wires.
• Electrical conduction: Delocalized electrons flow through the lattice structure when a voltage is applied to a metal. An electric current is formed by the movement of these charged particles. The metal ions in the metallic lattice are not able to migrate and are maintained in fixed locations.

Difference between Metals & Non-metals:

1. Metals are ductile and malleable. Non-metals are poor heat and electrical conductors. Graphite, on the other hand, is a good conductor of electricity.  
2. Metals are excellent heat and electrical conductors. Metals are fragile, while nonmetals aren't (break easily). They aren't malleable or ductile in the least.
3. At room temperature, metals are solids. Mercury, on the other hand, is a liquid metal. At room temperature, non-metals might be solids, liquids, or gases.
