Question

Which element is least likely to conduct heat and electricity?

Ca

Si

Po

O


what the answer ?

Answer 1

Answer:

Non-metals are least likely to conduct heat and electricity. So, among these Oxygen (O) is most non-metallic. Thus it is least likely to conduct heat and electricity.

hope this will help you

Answer 2

The element Oxygen is least likely to conduct heat and electricity. ( Option d)

• Generally, metals are good conductors of heat and electricity. Almost, all the metals from the periodic table are good conductors of heat and electricity.
• Metalloids are not as efficient as metals in terms of conducting heat and electricity. Metalloids are not insulators like non-metals, they conduct heat and electricity but they do not conduct as fast as metals generally conduct.
• Non-metals are considered as insulators, Insulators generally do not conduct electricity as they do not have any metallic properties in them, Hence Non-metals do not conduct heat and electricity.

From the given options,

• Calcium (Ca) is a metal, So it conducts heat and electricity effectively.
• Silicon (Si) is a metalloid, Hence it conducts heat and electricity at a low rate.
• Polonium (Po) is a metal, Hence it conducts heat and electricity.
• Oxygen (O) is a non-metal, Hence it doesn't conduct heat and electricity. (Non-metal generally do not conduct).

Hence, Option D (O - Oxygen) is the correct answer.
