Question

Which element is malleable and a good conductor of electricity at STP?

Answer 1

Answer: The correct answer is option(4).

Explanation:

Malleability : It is a property of a material that under the pressure they can be drawn into thin sheets.

Conducting: It is a property of a material to allow electric current to easily pass through it.

Since both the above properties are of metals. And from the enlisted elements only one element is metal that is 'silver'.

So, the correct answer is option(4).

Answer 2

$\boxed{\left( 4 \right){\text{ silver}}}$ is the element that is malleable and a good conductor of electricity at STP.

Further Explanation:

The representation of all the elements in their increasing atomic numbers is known as the periodic table. Such a representation is done in the form of a table having horizontal rows called periods and vertical columns called groups.

Malleability is the property of substance due to which it can be deformed by applying pressure. The malleable materials can be drawn into thin sheets by the process of rolling or hammering. Metals are malleable in nature because these have the tendency to get deformed under pressure.

Any substance that allows the flow of electric charges through it is said to be a conductor. Conductivity is defined as the property of any conductor to permit the flow of charges through it. Metals are good conductors of heat and electricity due to the presence of free electrons in them. Such electrons act as charge carriers.

Both malleability and conductivity are the properties of metals. Since silver exists as a metal at STP, it is malleable and a good conductor of electricity. But carbon, argon and iodine are non-metals at STP so these cannot exhibit any of the mentioned properties. Therefore option (4) is correct.
