Which lists the elements in order from most conductive to least conductive?

A.) potassium (K), selenium (Se), germanium (Ge)

B.) germanium (Ge), potassium (K), selenium (Se)

C.) selenium (Se), germanium (Ge), potassium (K)

D.) potassium (K), germanium (Ge), selenium (Se)

Answer 1

B) They want the electric current to be carefully controlled so they use a metalloid as a semiconductor.

D)bismuth (Bi), antimony (Sb), nitrogen (N) because of the number of free electrons in the lattice.

C.) selenium (Se), germanium (Ge), potassium (K)
again because of the free electrons in the lattice.

Hope this helps.

Answer 2

Correct answer choice for question 1 is :

B.) Metalloids are semiconductors.

Explanation:

The form, design, and implementation of CPUs have replaced over the track of their past, but their primary process continues almost constant. Principal parts of a CPU involve the arithmetic logic unit (ALU) that executes arithmetic and logic operations, processor registers that provide operands to the ALU and save the results of ALU operations and a control unit that organizes the fetching and performance of directions by directing the coordinated operations of the ALU, registers and other elements.

Correct answer choice for question 2 is :

D) Bismuth (Bi), antimony (Sb), nitrogen (N) because of the number of free electrons in the lattice.

Explanation:

The most conductive of all metals are silver, copper, and gold in that order. Silver is also the common thermally conductive component, and the maximum light reflecting component. Silver also has the unique feature that the tarnish that develops on silver is still extremely electrically conductive. Silver also has the greatest thermal conductivity of any component and the leading light reflectance.

Correct answer choice for question 3 is :

C) Selenium (Se), germanium (Ge), potassium (K)

again because of the free electrons in the lattice.

Explanation:

The most highly conductive metals are silver, copper, and gold. Copper is highly conductive and commonly used in metal cables. Brass includes copper but other materials in its makeup decrease conductivity. Pure silver is the most conductive of all metals. Metals always have free electrons, that's what gives them a good conductor of electricity. Stainless steel may be the least conductive metal, but it still does carry electricity more efficiently than many other matters. In case, below normal circumstances, no material is completely non-conductive.
