Ionization Energy: What Makes Inert Gases Special?

[thabo2g5]

please can someone explain to me what is ionization energy and how come inert gases seems like they are special

 

[malawi_glenn]

ionaziation energy is the energy to remove an electron from an atom (to ionize the atom)

 

[amanmahadeshwar]

The ionization energy or ionization potential is the energy necessary to remove an electron from the neutral atom. It is a minimum for the alkali metals which have a single electron outside a closed shell. It generally increases across a row on the periodic maximum for the noble gases which have closed shells.

Noble gases really catch hold of their electrons very firmly and the e- too have no reason to leave thus U will need a very large amt. of energy to rip out an e-

 

[zapta]

The energy required to remove one e- from the valence shell of a neutral atom.
It is hence the energy required to ionize the atom (+1 charge)

 

[i.mehrzad]

Well it is better to state that it is the energy required to remove an electron from an isolated gaseous atom.

 

[hagopbul]

and in crystal you can use this equation
$$\phi$$=$$\frac{\lambda A_{n}}{R^{n}}$$ -$$\frac{\alpha e}{R}$$

e=electron charge

what does one mean by 'special'.

Inert gases are relatively 'inert', i.e. they do not readily react chemically with other elements. This is because of the higher binding energy of the last electron.

The halogen F does react with Kr and Xe form compounds.
