What is the charge on the cation of calcium and aluminium when they lose their valence electrons?
Yay Chemistry! Alright so Lithium is closer to losing electrons so it will become He by losing an electronOxygen is closer to the right of the periodic table and therefore will gain electrons so its charge will become a -2 to become like NeonSulfur is also like oxygen and will have a -2 charge and be like ArgonAluminum will most likely lose three electrons and become like Neon as well with a +3 charge
lithium can be formed with oxygen and aluminum can be formed with sulfer
Calcium is 2+ and Aluminum is 3+The reason why the charge is stated this way (number then + or -) is because this is how the rules were setIons are this way and oxidation numbers are the other way (+ or - then number).
