Question:

How do you know what noble gas these have the same electron configuration as these ions?

a) cesium sulfideb) strontium flouridec) calcium nitrided) aluminum bromideHow do you figure this out?Thanks in advance!

Answer:

FOR ONE THING I DONT USE ALUMINUM POTS AND PANS, THE METAL LEACHES ONTO THE FOOD AFTERWHILE.
Because the pot is not made out of aluminumIt is COATED with aluminumMeaning if you use something too abrasive, you will SCRAP OFF the COAT of aluminum.
Because the sand paper or steel wool will leave big old scratches in them and make the pans even more likely to stickI use commercial aluminum baking sheets and if a nylon scrubber won't take something off, I use Barkeeper's FriendThe Barkeeper's is a powdered cleanser that works great on metal and it's cheap! It's not nearly as harsh as regular scouring powder but gets the gunk off! Proper preparation of the pans before use does help eliminate a lot of issues.
You need to know the charges on ions in compounds Much of this knowledge is obtained from a knowledge of the periodic tablea) cesium sulfide is Cs2S, the ions are Cs^+ and S^2- When Cs loses an electron it becomes Cs^+ and has the same electron configuration as Xe When S gains 2 electrons it becomes S^2- and has the same electron configuration as Ar b) strontium flouride is SrF2; the ions are Sr^2+ and F^- When Sr loses 2 electrons it becomes Sr^2+ and has the same electron configuration as Kr When F gains 1 electron it becomes F^- and has the same electron configuration as Ne c) calcium nitride is Ca3N2; the ions are Ca^2+ and N^3- When Ca loses 2 electrons it becomes Ca^2+ and has the same electron configuration as Ar When N gains 3 electrons it becomes N^3- and has the same electron configuration as Ne d) aluminum bromide is AlBr3; the ions are Al^3+ and Br^- When Al loses 3 electrons it becomes Al^3+ and has the same electron configuration as Ne When Br gains 1 electron it becomes Br^- and has the same electron configuration as Kr I used the periodic table to help obtain the answersHope this is helpful.
