What is ionization enthalpy ? On what factors does it depend ? How does ionisation enthapy of the elements very as we move down a group and along a period ? View Solution How does the ionization energy of first group elements vary?
As down a group Trend: decreaseReason: The increasing of shielding effect by inner shells and the increasing of size of atom outweigh the increasing of proton numbers. So attraction between nucleus and outmost electrons becomes weaker and weaker and less energy is needed to remove the electron aw...
Ionisation energy increases on moving down a group in the periodic table. View Solution Why does the stability of + 3 oxidation state decrease on moving down the group 13 ? View Solution State whether the ionization potential decreases on going down a group. ...

Practical difficulties arise from the impossibility of obtaining any instrument with absolutely constant zero; moreover, fluctuations in the intensity of the energy stream from the source of radiation, repre- sented by the Nernst filament, would cause trouble ©1913 Nature Publishing Group ...
We obtain reaction rates in merge beam experiments, over a wide range of collision energies corresponding to that of room temperature, all the way down to a few millikelvins. We observe a change of two orders of magnitude in the branching ratio in the measured collision energy range and ...
<p>To determine which of the following elements has the largest ionization energy among scandium, zinc, cadmium, and mercury, we can follow these steps:</p><p><strong>Step 1: Understand Ionization Energy</strong> Ionization energy is the energy required
The factors responsible for the ionization enthalpy of the main group elements to decrease down a group are listed below: (i) Increase in the atomic size of elements: As we move down a group, the number of shells increases. As a result, the atomic size
