Is it easier to remove an electron from Cs or Ba? Explain
Homework Answers
First of all Cs, Ba are belong to same group in the periodic table. Cesium is first A group and Ba is second A group elements.
In periods, from left to right size of the atom decreases. So if the size is reduced means the effect of nuclues is more on the valence electrons of smaller sized atom. In such cases it is very difficult to remove an electron from that atom.
In between Cs and Ba , Ba is smaller in size. So difficult to remove an electron from Ba than Cs.

Explain the large increase in ionization energy needed to remove the third electron from beryllium compared with that needed for the second electron. Removal of the third electron requires more energy because it must be removed from a 2+ beryllium ion, which has a(n) _____ ( Stable or Unstable) electron configuration, the same configuration as .

The energy required to remove an electron from a surface of a solid element is called its work function. If a minimum of 431.3 kJ/mol is required to remove electrons from Cu atoms on a surface of a sample of copper, what is the maximum wavelength (λmax) of light that can remove an electron from a Cu atom on this surface? If the same copper surface is irradiated with light of λ=153.8 nm, what is the maximum kinetic energy that...
