Which element is a brittle solid with low conductivity at STP?
(1) sulfur (3) argon
(2) sodium (4) aluminum


Sagot :

Sulfur is the element that is a brittle solid with low conductivity at STP.

Answer: option (1) sulfur.


Explanation:


1) Brittleness and low conductivity are known properties of solid non-metals.


2) On the contrary, solid metals are known for their ductibility, malleability, and high electrical and thermal conductivity.


3) Sulfur is a non-metal,solid at STP (standard temperature and pressure), so you can expect that it is brittle and a poor conductor.


4) Sodium is a metal, hence it is ductile, malleable and good conductor of electricity and heat.


5) Argon is a non-metal gas at STP, ergo it is not solid.


6) Aluminun is a metal, so it is also ductile, malleable and good conductor.
