प्रश्न
Give a reason for Ionisation potential increases across a period, from left to right
Advertisements
उत्तर
From left to right in the periodic table, atomic size decreases smaller the size more the effective nuclear charge. Therefore more energy is required to remove an electron from the atom, therefore, ionization potential increases.
