Question

atomic number of elements xy and z are 4,11,12 which element has highest ironisation energy? why?

Answer 1

Hi

The element Z has higher ionisation enthalpy value. Because as the atomic size increases the attractive force of nucleus on the outermost electron decreases ans so ionisation enthalpy decreases.

Answer 2

The element with highest ionisation energy is the one with the lowest atomic number. So the element with atomic number 4 will have the highest ionisation energy.

In material science and science, ionization vitality or ionization vitality, signified Eᵢ, is the base measure of vitality required to evacuate the most approximately bound electron, the valence electron, of a disengaged nonpartisan vaporous iota or particle.
