Question

among the elements Li, Na, Mg, S and Xe which one has the lowest and the highest first ionization enthalpy?​

Answer 1

Answer:

The highest IP of the element = Xe.

The lowest IP of the element = Na...

Answer 2

Xe has the highest ionization enthalpy and Na has the lowest ionization enthalpy.

Explanation:

• Ionization energy or Ionization enthalpy of elements is defined as the amount of energy required by an isolated gaseous atom to lose an electron in its ground state.
• The first ionization energy is the energy required to remove one mole of the most loosely held electrons from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+.
• This is more easily seen in symbol terms.
