Question

The table shows the electronegativity values of four unknown elements on the Pauling scale. Electronegativity Values Unknown Element Electronegativity P 2.55 Q 3.98 R 1.31 S 2.5 Which two elements are most likely to form an ionic bond together? P and Q Q and R R and S P and S

Answer 1

Q and R

Step-by-step explanation:

Answer 2

Q and R are most likely to form an ionic bond.

Step-by-step explanation:

Ionic bond is formed between two elements which have huge difference in their electronegativities.

According to the given question the electronegativity difference of QR is greater than that of PQ, RS and SP.

From this point of view it can be stated that Q and R are most likely to form an ionic bond.
