Answer 2

$\huge{\orange{\underline{\red{\mathbf{ANSWER}}}}}$

1. There is a sudden decreasing in the ionisation energy from He to Li, because 'He' is noble gas and 'Li' is electropositive element.
2. Noble gas elements have highest I.P.E values , they cannot lose electrons, easily due to more stable configuration.
3. Na and K have less I.P.E values because thay have only 1 and 2 electrons in valency respectively and they easily lose these electrons to get stability.
4. I.P.E values are not followed a particular trend while going from left to right in the periodic table.
