Differentiations - Metal and Non-metal

Question

Differentiate Metals and non-metals by giving 2 main points

Answer 1

Metals and non-metals are quite different in their properties. Here are two main points to differentiate them:

1. Conductivity: Metals are excellent conductors of heat and electricity, while non-metals are generally poor conductors. This is because metals have free electrons that move easily, carrying energy.

2. Physical State and Appearance: Metals are usually solid at room temperature (except mercury), shiny, and malleable, meaning they can be hammered into thin sheets. Non-metals can be solid, liquid, or gas, and they tend to be dull and brittle, meaning they break or shatter when struck.

Answer 2

Differences Between Metals And Non-metals:

Metals	Non-metals
These are solids at room temperature except mercury	These exist in all three states
These are very hard except sodium	These are soft except diamond
These are malleable and ductile	These are brittle and can break down into pieces
These are shiny	These are non-lustrous except iodine
