Question

among the compounds NaCl KCL rbcl and cscl the one with greatest ionic character​

Answer 1

Answer:

Explanation:

the order in which the ionic character of the bond between the following compounds is as follows :

CsCl>RbCl>KCl>NaCl

This is due to the reason that keeping the anion constant in this case Cl, when the cation’s size size is increased the tendency of the atom to lose the last electron increases with atomic size and the atomic sizes are as follows :

Na<K<Rb<Cs

This is because the nuclear pull of the electron that is in the last shell is least when the atomic size is the greatest

Answer 2

Explanation:

Answer:

Explanation:Compounds having the greatest ionic character-RbCl

Least ionic character-BeCl2

as we know that on going along the period the electronegativity increases and on going down the group electronegativit decreases.  The aninoinc part here is same,therefore the cation having more electronegativity have more covalent character.

Electronegativity order is Rb<Li<Mg<Be  Thus it can be seen that the percentage of ionic character is directly proportional to the electronegativity of the element
