Which noble gas is isoelectronic with Ba2+?
The electron configuration of Ba2+ is isoelectronic with the noble gas: Kr b.
How many valence electrons does Ba2+ have?
From the Ba2+ lewis structure, the electronic configuration of Ba2+ is 1s22s22p63s23p63d104s24p64d105s25p65d10. So, the outer most shell will be 5d orbital and there are 10 electrons present so the shell in fully completed and those are the valence electrons for Ba2+.

Which has more size Cs+ or Cl?
In crystal ionic radii, chloride is smaller than caesium and fracium while the latter two’s effective ionic radii are larger than chloride’s.
Which of the following has the largest size a Cs+ b f/c Cl D K+?
Cs+ has highest ionic radii as it is on the extreme right corner of the table. So it is highest in it’s period and highest in the group.
