Front

What are semiconductors?

Back

Semiconductors are materials that have electrical conductivity between conductors and insulators, typically metalloids.

Front

Define conductivity.

Back

Conductivity is the ability of a material to conduct thermal or electrical energy.

Front

What does ductility refer to?

Back

Ductility is the ability of a material to be pulled into a wire.

Front

What type of elements are located in the upper floating row of the periodic table?

Back

The upper floating row of the periodic table contains Rare Earth elements.

Front

How can properties be used in chemistry?

Back

Properties can be used to identify elements from each other.

Front

What are metalloids?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals, and they are often semiconductors.

Front

What is the significance of Rare Earth elements?

Back

Rare Earth elements are crucial for various technologies, including electronics, magnets, and batteries.

Front

Explain the difference between conductors and insulators.

Back

Conductors allow the flow of electrical current easily, while insulators resist the flow of electrical current.

Front

What is the role of temperature in conductivity?

Back

Temperature affects conductivity; generally, as temperature increases, the conductivity of metals decreases, while that of semiconductors increases.

Front

What is the relationship between ductility and malleability?

Back

Ductility is the ability to be stretched into a wire, while malleability is the ability to be hammered or pressed into shapes without breaking.
