State any five physical properties of metals and five physical properties of non-metals.

Five physical properties of Metals

The following are the physical qualities of metals:

• Metals are ductile and malleable.
• Metals are efficient heat and electrical conductors.
• Metals can be polished and are lustrous (shiny).
• Metals at normal temperature are solids (except mercury, which is liquid).
• Metals are resilient and powerful.

Chemical Properties of metals –

1. prone to corrosion
2. possible electron loss
3. creating basic oxides
4. possess a low electronegativity
5. Good reducing substances

Five physical properties of Non-metals

• The non-metal world is fragile. They are neither ductile nor malleable.
• Non-metals are poor heat and electrical conductors (except graphite).
• Non-metals are dull and cannot be polished because they lackluster (except iodine).
• At room temperature, non-metals can exist as solids, liquids, or gases.
• Non-metals lack both toughness and strength.

Chemical properties of non-metals –

1. In the outer shell, there are typically 4 – 8 electrons.
2. simple acquisition or loss of valence electrons
3. whenever they come into touch with oxygen, they produce acidic oxides.
4. Extremely electronegative substances
5. excellent oxidizers

Summary:

State any five physical properties of metals and five physical properties of non-metals.

Metals have ductile and malleable physical characteristics, are excellent heat and electricity conductors, and are naturally shiny. Non-metal physical characteristics include brittleness, poor heat and electrical conductivity, and lack of luster.
