Use the periodic table to answer the question.

An illustration shows the periodic table of elements. The elements in the periodic table are arranged in groups (columns numbered 1 through 18) and periods (rows numbered 1 through 7) such that the atomic number increases along a period from left to right. The elements are divided into the following categories: · Alkali metals · Alkaline earth metals · Transition metals · Post-transition metals · Lanthanides · Actinides · Metalloids · Nonmetals · Noble gases · Unknown The elements are also classified on the basis of their physical states as follows: · Solid · Liquid · Gas · Unknown The element sulfur is enlarged with the following properties. · Chemical symbol: S · Name: Sulfur · Atomic Number: 16 · Atomic mass: 32.06 · Common oxidation states: 6, 4, 2, negative 2 · Electronegativity: 2.58 · Ionization energies: 999.589 · Electron configuration: [Ne] 3s2 3p4

To determine which element is the best conductor of thermal energy among the options provided, we can evaluate the general properties of the elements listed:

  1. Argon (Ar): A noble gas, known to be poor in thermal conductivity because it is non-metallic and exists as a gas at room temperature.

  2. Vanadium (V): A transition metal, known for good thermal and electrical conductivity.

  3. Germanium (Ge): A metalloid, which has moderate conductivity but is generally not as conductive as metals.

  4. Polonium (Po): A post-transition metal that can conduct heat but is typically not known for excellent thermal conductivity; however, it is more conductive than metalloids and nonmetals.

Of these options, Vanadium (V) as a transition metal is known for its excellent conductivity. Therefore, it is the best conductor of thermal energy among the choices given.

The best answer is vanadium (V).
