Answer:
Aluminium
Explanation:
Ionization energy is the amount of energy needed to remove an electron from a gaseous atom to form a gaseous ion.
The difference between the third and fourth ionization energies is great. This indicates a group III element which is in the third period.
This element is Aluminium (Al)
Metalloids are all solid at room temperature<span>. Some metalloids, such as silicon and germanium, can act as </span>electrical<span> conductors under the right conditions, thus they are called semiconductors. Silicon, for example, appears lustrous but is not malleable or </span>ductile<span> (it is brittle - a characteristic of some nonmetals).

Answer:
Reaction equilibrium will shift to the left (higher molar volume side of process).
Explanation:
For gas phase reactions, changes in pressure-volume conditions cause a stress on the process equilibrium shifting away from the applied pressure-volume change.
LeChatlier's Principle states for a gas phase reaction at equilibrium ...
if the pressure is increased (volume decreased) the reaction will shift toward the lower molar volume side of the process.
if the pressure is decreased (volume increased) the reaction will shift toward the higher molar volume side of the process.
if the sum of molar volumes of reactants equals the sum of molar volumes of products, changes in pressure-volume conditions will NOT affect the equilibrium stability. Example => H₂(g) + Cl₂(g) ⇄ 2HCl(g) will not be affected by P-V changes as ∑Vm(reactants) = ∑Vm(products).
