how do i compare ionic radaii?
for example how do i deretmine which is bigger between Ca2+ and Cl-?

Question

anonymous · Answer

atomic radii is one of the common trends in the periodic table it increase moving down and to the left corner

anonymous · Answer

so can i just ignore the 2+ and - sign and just follow the trend?

anonymous · Answer

the 2+ denotes the protons attached to the metal calcium and the negative electron attached to chlorine, the ionic spacing between the two elements should be equal to the addition of their atomic radius which are constant

anonymous · Answer

calcium has a larger radius because it is positioned on the left hand side of the table

alright ty i know this is not math but the chem section is kinda slow
