Halogen with highest ionization enthalpy is ͟ ͟ ͟͟͟

The family of elements with the highest ionisation enthalpy:

In the following, the element with the highest ionization energy is

Among the elements of the third period, identify the element. a) With highest first ionization enthalpy. b) That is the most reactive metal. c) With the largest atomic radius.

Don't you think that there is a relationship between ionization energy and metallic non metallic character? Is the element with highest ionization energy metallic or non metallic?

a) Which of the following has higher first ionization enthalpy, N or O? Justify. b) Which one is bigger, F or F^- ? Why?

Define ionization energy?

Among the elements B , Al , C and Si . a. Which has the highest first ionization enthalpy? b. Which has most negative electron gain enthalpy? c. Which has the largest atomic radius? d. Which has the most metallic character?

Why does the first ionization enthalpy increase as we go from to across a given period of the Periodic Table?

The reactivity of an element is very much related to its ionization enthalpy. Observe the following graph in which the first ionization enthalpies (DeltaH_1) of elements of the second period are plotted against their atomic numbers (Z): Identify the anomalour values and justify.
