| What is the first ionization equation of Ne? | Ne(g) -----> Ne+(g) + e-
🗑

| What are the three factors effecting ionization energy? | Nuclear Charge
Atomic Radius
Electron Shielding
🗑

| Why are successive ionization energies larger than the one before? | As each electron is removed, there is less repulsion between the electrons and each shell will be drawn in to be slightly closer to the nucleus
As the distance of each electron from the nucleus decreases slightly, and nuclear attraction increases.
