1. Define and predict trends in atomic radii, ionic radii, ionization energy and electron affinity by using the periodic table.

2. Differentiate between ionization energy and electron affinity

3. Place the following atoms in order of increasing atomic radius: N, O, P, Ge

Expert Solution

atomic radii: The distance between center of nucleus and outer most shell is called atomic radus of the atom.

or

Haf of the distance between the two bonded aoms is called atomic radii

ionic radii: Haf of the distance between theions is called ionic radii

ionization energy : The amount of energy is required to remove an electron form its nutral atom is called ionisation energy.It is endothermic reaction delta H is positive

M(g) ----------> M^+(g) + e^- IP = +ve

electron affinity:The amount of energy is released whan an electrons is added to isolated gas atom is called electron affinity. it is exothermic reaction deltaH is negetive.

X(g) + e^- -----------> X^- (g) Ea = -ve

Periodic Trends - Ionization Energy Name Chem Worksheet 6-4 Ionization describes the process in which an electron is removed from an atom in the gaseous state. The amount of energy required to remove the outer electron is called the first ionization energy. Successive electrons can be removed as well.
