Definition me 'gaseous' aur 'isolated' kyun likha hota hai?

Taaki electron nikalte waqt koi doosra atom ya phase interaction disturb na kare — pure single atom se ek electron, vacuum me. Tabhi value standard aur comparable hoti hai.

IE₂ hamesha IE₁ se zyada kyun hoti hai?

Ek electron nikalne ke baad cation ban jata hai; ab kam electrons par utna hi nuclear charge — baaki electrons zyada zor se khinche jaate hain, isliye agla nikalna mushkil.

Be ki IE₁, B se zyada kyun hai jabki B ka Z bada hai?

Be ka 2s² fully-filled stable hai; B ka 2p¹ electron tulna me kam strongly bound hota, easily nikal jata — isliye Be ka IE zyada.

Ionisation Enthalpy — Pull an Electron

Classification of Elements & Periodicity

Strip electrons one by one off an isolated gaseous atom and feel the grip get stronger. Watch the energy jump when the noble-gas core breaks — that jump tells you the group.
