Here's another physics question for you geniuses out there.?

The alkali metals (group 1) tend to form 1+ ions while alkali earth metals (group 2) tend to form 2+ ions because:


a. alkali metals are less massive


b. this is a random occurence


c. the changes of these ions corresponds to the number of valence electrons that may be lost


d. the ion an atom forms is always equal to the group number





only answer if you know for sure

Here's another physics question for you geniuses out there.?
C, and this is chemistry. Atoms in these groups have extra electron(s) in their outer shell. All atoms want to have a full valence shell, (or empty depending on how you look at it), so if these want to get rid of the extra electrons they have.
Reply:Thank you! Glad I could help. Report It

Reply:Yeah, it's C. Just confirming.
Reply:c
Reply:C is more appropriate.





Every element in a group has the tendancy to form ions. It depends on the stability of the ion but not the group number always. But in the first 2 to 3 groups, it is possible. Then onwards there will be a slight change in this due to inert pair effect.





In case of 1,2,3 and slightly 4 or 5 group elements the changes of these ions corresponds to the number of valence electrons that may be lost. So the option C is correct.





Hope you had understood this explanation.
