1 thought on “<br />Justify the statement, bigger size atom<br />have low <br />ionization energy & have more<br />Shielding<br />effect?”
Answer:
Ionisation energy:
it is defined as the energy required to remove a valency electron from a atom.
usually nucleus attracts all the electrons we have two types of electrons
1.valency electrons
2.core electrons
core electronsarethe electrons other than valency electrons.
Shieldingeffect:
opposition of valency electrons by core electrons against the attraction of nucleus.
Explanation:
as the largeatom contains more electrons , core electrons aremore so that the shielding effect is more
so the shielding effect is more attraction force of nucleus on valency electrons is less os we can easily remove the valency electrons hence ionisation energyis low
