Question

Which of the following has the largest I\(_2\)? (Transition metals lose their \(s\) electrons before the \(d\) electrons)

K
Ca
Sc
Fe

Answer 1

@Preetha

Answer 2

I2? Second ionization energy?

Answer 3

yes

Answer 4

I leave now, but please leave a response, thanks

Answer 5

Write the electron configuration of all the atoms. Then see which electron will be removed in the second ionization reaction. Then think about which electron would be the hardest to remove. I think you will see it. For example, K has to lose its s electron first and then it will lose an electron from a closed inner orbital, the p. Now do the same for the rest of the atoms.

Answer 6

Okay, I'll try that... thank you!

Answer 7

\[K:~ 1s^1~ 2s^2~ 2p^6~ 3s^2 ~3p^6~4s^1\]\[Ca:~1s^1~ 2s^2~ 2p^6~ 3s^2 ~3p^6 ~4s^2\]\[Sc:~1s^1 ~2s^2 ~2p^6 ~3s^2~ 3p^6 ~4s^2~ 3d^1\]\[Fe:~1s^1~ 2s^2 ~2p^6 ~3s^2~ 3p^6~ 4s^2~ 3d^6\]

Would it be K?

Answer 8

@Preetha

Answer 9

@Australopithecus got anything?

Answer 10

Pretty sure Ionization energy is related to effective nuclear charge (electronegativity)

Answer 11

yes i believe so

Answer 12

Ca is more electronegative than K, (it is closer to the right the periodic table)

Answer 13

yea but it says SECOND Ionization energy so.. idk :\ im confused

Answer 14

Isn't there a law where available orbitals are filled with 1 electron before they are filled with 2

Answer 15

I think you are over thinking it

Answer 16

Anyways if something has a strong affinity for electrons (it is electronegative) it should take even more energy to pull the next electron off it

Answer 17

yea but we're talking about pulling the second electron off

Answer 18

let me read up on orbitals, I haven't done this stuff in ages

Answer 19

and wouldnt K use the most energy since its stable after the first electron being removed so it would take a lot more energy to remove a second one

Answer 20

what is the point of this question?

Answer 21

Which of the following has the largest I2? (Transition metals lose their s electrons before the d electrons)

K
Ca
Sc
Fe

they want to know which element would have the largest second ionization energy

Answer 22

the more you go toward to the right, the ionization energy increases.
so it's
down to up
left to right
and diagonal right

Answer 23

there's a chart of a whole periodic table on this one. let me pull it up for you

Answer 24

I posted it I'm pretty sure @nincompoop

Answer 25

i answered Fe since its farthest to the right as would follow the rule but my teacher said to try again cuz that was wrong..so i honestly dont even know

Answer 26

that is because d orbitals dont hold electrons very well, wish I knew why tbh

Answer 27

It is why metals are conductive though

Answer 28

okay so Sc and Fe are ruled out, yea?

Answer 29

any way you can just link the index?

Answer 30

This looks like an interesting book, I really wish I could take inorganic chemistry and structure and bonding

Answer 31

tha pages end at 110..

Answer 32

you have to look at the displayed page on the book itself, don't follow how it shows on your browser or adobe. I took every chapter individually so it is easier for people to download or view

Answer 33

yea the individual page numbers end at 110

Answer 34

okay look at the upper right and upper left hand corners of the book, it tells you the actual page in the book itself.

Answer 35

I just got home, so let me settle down and I will help you later.

Answer 36

nin im not stupid...the header on the last page says:
110- Chapter Two Atomic Structure and Periodicity

Answer 37

Thanks nincompoop this is a great source

Answer 38

it is :)

Answer 39

umm...i think i got it, I'll put some more thought to it and ask my instructor again later
Thanks guys!
