Question

Which of the following statement is correct about Metals ?
1. Metals are Lustrous
2. Good conductors of heat & electricity
3. Malleable
4. All of the above

Answer 1

Correct Answer - Option 4 : All of the above

The correct answer is All of the above.

• Metal is (any of a class of substances) characterized by high electrical and thermal conductivity as well as malleability, ductility, and high reflectivity of light.
• The most abundant varieties in the Earth’s crust are aluminum, iron, calcium, sodium, potassium, and magnesium.
• Metals are usually crystalline solids.
• Metals are Lustrous.
• Metals differ widely in their chemical reactivity.
• The most reactive include lithium, potassium, and radium, whereas those of low reactivity are gold, silver, palladium, and platinum.
• Thperiodic table) are best explained by using the free-electron theory.
