It would be classified as decomposition reaction
A) The bond that will be formed by these elements is : <u>Ionic Bond </u>
B) Group 1 elements Gives up its electron to Group 17 elements
<h3><u /></h3><h3><u>Electronegativity values </u></h3>
From the electronegativity values given in the question group 17 elements with an electronegativity value of 2.99 are more electronegative than group 1 elements with a value of 0.84. Therefore they accept electron transfer from group 1 elements.
The acceptance of electrons from group 17 elements leads to formation of an ionic bond between group 1 and group 17.
Hence we can conclude that the bond that will be formed by these elements is Ionic bond and Group 1 elements gives up its electron to group 17 elements.

Answer:
the solubility of the ionic solid decreases
Explanation:
If a salt MX is added to an aqueous solution containing the solute AX, the X^- ion is common to both of the salts. The presence of X^- in the solution will suppress the dissolution of AX compared to the solubility of AX in pure water. This observation is known as common ion effect in chemistry.
The origin of common ion effect is based on Le Chatelier's principle. The addition of a solute will drive the equilibrium position towards the left hand side.
