Web18 uur geleden · You can see that the ionisation energies tend to fall as you go down the Group - although there is a slight increase at lead. The main trend is because: The atoms are getting bigger because of the extra layers of electrons. The further the outer electrons are from the nucleus, the less they are attracted - and so the easier they are to remove. WebIonization energy is the amount of energy necessary to remove an electron from an atom. The ionization energy tends to increase from left to right across the periodic table because of the increase number of protons in the nucleus of the atom. It tends to decrease down a column of the periodic table because the number of electron shells is larger, making …
