Identify which trends in the diagrams below describe atomic radius, ionization energy, electron affinity, and electronegativity.

a)  figure describe ionization energy , electron affinity & electron negativity

b) figure describe Atomic Radius

c) does represent anything

Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element.       H-->Cl

Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy.   M + IP> M+ + e-

Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.

   X + e- > X- =- EA

Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
