Which of the following ions has the electron
configuration of a noble gas: $\mathrm{Ca}^{+}$ or $\mathrm{Cl}^{-} ?$
(Hint: Write the electron configuration for
each ion.)

All right. So we have another question. It's serious that given the electron configuration this one And we are required to give an iron that has a charge of plus one with that electron configuration. Now, if an iron has a charge of plus one, it means it's last one electoral At last one electron. Now the total number of electrons for this one uh is 36 electrons. So if it had lost one electron then uh We had five s orbital that had one electron which was lost. Okay, So if we had lost that one electron and uh it's remaining 36 electrons that at that iron, The item of that iron has atomic Nemov 37. That is seven. So yeah, okay. Uh which element has the atomic number of 37 which is remedial. So rabi Media 37 and it last one electron. So that's plus one. And that is the iron that has that electron configuration yeah. Than be. Which I am with a charge of -2 -2 means that I am gain that item gained um two electrons against two electrons to form that I am. So it means that initially it has atomic it had uh 30 for electrons. It had 34 electors. And again Two more to get 36. So which item has atomic number of 34. Which is selenium good. All right. And it gained two electrons. So the charges -2. Oh, you can write it as linen two minus. So that's how that's one is done. Yes, Thank you.

Problem. 57 from Chapter six is asking us to find the ion with the plus one charge with the following electron configuration and the eye on with the minus to charge that has the same configuration. So to help us answer this question, um, I've referred to the electron configuration table that is located in the text s 02 1st figure out which, um, the cat eye on with the plus one charge that has this electron configuration. The original Adam must have lost an electron. So previously it must have had a five s one. So this is for the cat eye on so five s one. We get rubidium, but not lost that electrons. So now has this configuration here and then for the cat. I Excuse me, the an eye and with the same configuration, it must have gained two electrons to reach this electron configuration. So its original electron configuration must have been four p for so if we go to the electron configuration table, um, we can see that selenium has four p four, so it must have gained two electrons to then have this electron configuration. So selenium and rubidium

In order to have the same number of electrons as sulfide, wouldn't know how many drums it does have. Phil for has 16 electrons with the Tu minus charge. It has two more so 18 electrons chloride chlorine has 17 elect drums with one more for the one minus charge. It has 18. So yes, it's the same sold fight. Calcium two plus has 20 removed two electrons. Now there's a team, so yes, it's the same Sulfide Sodium has 11 electrons. You remove one. Now it only has 10. So no, it's not the same sulfide oxygen as 12 electrons We removed oxygen has eight electrons. We add two now has 10. So it's not the same as sulfide. Boss. Phosphorus has 15 electrons. We add three more with a three minus charge. We have 18. So yes, this is the same as sulfide

Taking a look at noble gas configurations and iron configurations to see which are the same. So we have B A two. Plus, This is analogous to Xena. Next we have s two minus. This is analogous to bargain. Following this, we have s r two. Plus, this is analogous to Krypton. Next we have f minus that's analogous to neon. Next we have mg to cliffs. That's analogous to me in two. Next we have go to minus. That's analogous to neon. One of in this we have a l three plus also in August Neon. Lastly, we have as to minus that is analogous to album. Wow, Wow.
