Neon has 10 electrons and krypton has 18 electrons which element do you think has a greater chance of forming a momentary dipole and why

krypton has more electrons, and it would have the greater chance of forming a momentary dipole.

Number of electrons in the atom

The number of electrons in each of the atom affect momentary dipole.

Momentary dipole

Momentary dipole is one of the London dispersion forces.  It is non-uniform distribution of electrons around a molecule, resulting in a temporary charge difference between its ends.

The number of electron in atom affects its polarization and the higher the number of electrons in an atom, the more easily the electron will move. krypton has more electrons, and it would have the greater chance of forming a momentary dipole.

Hello!

Krypton has a greater chance of forming a momentary dipole.

The momentary dipole is one of the London dispersion forces. It happens when in an apolar substance the electron density briefly moves towards a side of the substance, causing a difference in polarity and hence a momentary dipole. 

As chemical substance get bigger, their polarizability (ability to form a momentary dipole) is higher, since the higher amount of electrons makes they move more easily. So, as krypton has more electrons, it would have the greater chance of forming a momentary dipole. 

Have a nice day!

Sorry i dont understand the question can you rephase it?
