(a) NaCl > RbBr > CsBr
1.)The Cs cation is larger than the Rb cation.
2.)The ions in CsBr and RbBr are +2 and −2; whereas in NaCl they are +1 and −1.
3.)NaCl is smaller than RbBr and CsBr.
4.)CsBr is smaller than RbBr and NaCl.
5.)The Na cation is larger than the Cs cation.
6.)The ions in CsBr and NaCl are +2 and −2; whereas in RbBr they are +1 and −1
(b) SrO > SrCl2
1.)The oxide ion has a −1 charge; whereas the chloride ion is −2.
2.)The oxide ion is more electronegative than the chloride ion.
3.)The oxide ion is smaller than the chloride ion.
4.)The oxide ion is bigger than the chloride ion.
5.)The oxide ion has a −2 charge; whereas the chloride ion is −1.
