Identify the two elements which can form ions with the same electronarrangement as argon.Oxygen, Potassium, Phosphorous, Flourine, Lithium, Aluminium.What is the answer, and how is this worked out?
yes but only in a regular oven
yes, but not on the clean cycle
Argon has an atomic number of 18, with an electronic configuration of 2,8,8 Oxygen electronic structure 2,6 , not possible to add 10 electronsPotassium electronic configuration 2,8,8,1 Loss of an electron to form K+ ( potassium ion ) will give 2,8,8 Phosphorus electronic configuration 2,8,5 gaining 3 electrons will give 2,8,8 ( phosphide ion )Fluorine electronic configuration 2,7 not possible to add 9 electronsLithium electronic configuration 2,1 not possible to add 15 electrons Aluminium electronic structure 2.3 not possible to add 13 electronsAs you learn more you will understand bonding betterThe optimum arrangement is an outer shell of 8 electrons ( excluding hydrogen and lithium ) However the chemical nature of the material also mattersLithium would not be able to hold an additional electron, it would be stable forming Li+ losing an electronSo the answer is potassium losing 1 electron and phosphorus gaining 3 electrons
As long as its not a microwave oven, yes.
Yes you can but that is not the proper use or application for aluminum foil which is, of course, for making hats that keep aliens from being able to control your mindTake no chances, use two layers.
