Question

I dont understand periodic properties

Pre-activity: Periodic Properties 1. Write the equation that describes the first ionization energy (IE) of lithium. Include par 2. The orbital diagram of a lithium atom is shown below (left). Complete the orbital diagram for a lithium ion after ionization (IE; below right). + Ionization Energy Lithium atom Lithium after ionization 3. Write the equation that describes the first electron affinity (EA) of lithium. Include phases. 4. Complete the orbital diagram (below right) for a lithium ion produced by gaining an electron (electron affinity). tel Lithium atom Lithium after ionization 5. A lithium atom is more likely to react by losing / gaining ) an electron. 6. If lithium loses a valence electron, the ion's radius becomes (smaller / larger / no change) compared to the lithium atom. 201

Answer 1

Firest ionisation emoves encray is the outermost energy Bersy equired Letronsfrorn the Kelince shello In case of i - L I E Lit te laela-5- s t loai che This versu Lit 0+ electrons As 2s is so electron outermost shell, gor eject from ho 25 - 5 IS Lithium ion after tonischis Lithium Artom released First when electron affinity is the amount of energy an é is added to its outermost shell. for lithium, Lite Li + EA- This is electron affinity energy

5. A lithium ion is more likely to iloct by leasing electron Because, lithium has no of yeary less abfinity for e soit prefer to form cation. 6. when li looses és its ion's radius get smaller Earlier, nudeus has to hold 3e so less approach to now only two é are there so effective nuclear hoge get increased So, it holds e- more tightly So, radio's get smaller
