Answer:
CsCl
Step-by-step explanation:
The ionic species are:
Cs⁺ and Cl⁻
The two ions will combine to form an ionic compound which results from the electrostatic attraction between oppositely charged ions.
Elements or ions exchange directly their combining powers or their simplest whole number ratio during the formation of chemical formulae of compounds
Cs⁺ and Cl⁻
Combining power 1 1
Exchange of
valencies 1 1
