Question

what is ionisation energy explain the facters ​

Answer 1

• Basically there are five factors which can affect the Ionization energy like size of an atom,The effective nuclear charge,Shielding effect,Penetration effect and electronic configuration of an atom. All these factors related to the number of electrones in the valence shell and between the valence shell and nucleus.

Answer 2

${\huge {\underline {\underline {\sf {Answer}}}}}$

$\bigstar {\underline {\underline {\rm {Ionisation\:Energy}}}}$

Ionisation energy is basically the minimum amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated neutral gaseous atom or molecule.

$\bigstar {\underline {\underline {\rm {Factors\:affecting\:Ionisation}}}}$

• Atomic Radii

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

• Effective nuclear charge

The effective nuclear charge is the net positive charge experienced by an electron in a polyelectronic atom.

• Shielding effect

The shielding effect is when the electron and the nucleus in an atom have a decrease in attraction which changes the nuclear charge.

• Penetrating effect

Penetration describes the proximity of the electrons in a orbital to the nucleus.

• Stability of half filled and full filled orbits

Half filled and full filled orbits have greater stability then other particularly filled congregation.
