1)d

[@seemamalik2199]

1. Option d
2. Option b

[@manishakumawat3354]

H.W.
Que.1. Option (4) (Ne,Na) highest difference in their 1st I.E.
Que.2. Option (2) Hg>Zn>Cd

[@monayadav614]

1- option (d) bcoz as size increases l.E decrease so Ne>Ar>kr> Xe & Na>K>Rb>Cs decreasing order of I.E

[@sampurna-misschemico.]

H.W
1. Option 4 is correct ie. Ne and Na
2. Option 2)Hg>Zn>Cd
Thank you so much sir 🙏

You are welcome :)

[@Sumanyadv627]

H.w answer
Que 1) option 4 Ne Na
Que 2) option 2 Hg>Zn>Cd

[@triptidolai5226]

4 th option is correct Ne and Na bcz of size increases ionisation energy decrease, among the Nobel gas Ne ,Ar ,Xe, Kr ,Ne have highest IE bcz of less size on other hand Na ,K,Rb,Cs , is electropositive metal easily electron donate i.e why less inosation less energy,i.e why Ne and Na highest difference in IE.
Q2 . Hg > Zn > Cd

[@manishamishra3993]

Homework Ans :-
Q(1) Correct option (4) Ne, Na
Explanation -> Size increases, I.E. decreases
Among Nobel gases Xe, Kr, Ar, Ne
Size --> Xe> Kr> Ar> Ne
IE1 --> Ne > Ar > Kr > Xe
And among Cs, Rb, K, Na
Size --> Cs >Rb> K> Na
IE1 --> Na> K> Rb >Cs
Since Ne and Na have highest first I.E. thus this pair ( Ne, Na) has highest difference in their first I.E.
Thus option (4) is correct.
Q(2) 1st I.E. of the metals :
Correct option (2) Hg> Zn>Cd
Thank you so much sir 🙏

Sir apne arsenic n selenium ka configuration glt Liya h ?

[@mamatanishad9060]

Q1) correct option 4 Ne ,Na
Q2) correct option 2 Hg>Zn>Cd

[@sumaylasumayla1599]

Hw question 1)4 option correct Na and Ne question 2) Hg>zn >cd

[@pallaviyadav5599]

4 option ND 2 option

[@poojabajad5560]

Option 4 is correct because Ne and Na has highest difference in their first ionisation energy among noble gases Ne >Ar>Kr>Xe size increase and IE decrease.
Na>K>Rb>Cs size increase IE decrease hence option 4 is correct
Q.2 first ionisation energy order Hg>Zn>Cd

[@PallaviTripathi-n4q]

Ana 4correct Na and Ne
