P,Q,R,S are four elements. THeir atomic numbers are 8, 17, 12 and 16 respectively. Find the type of chemical bond in these compounds formed by combining the following pairs of elements. Construct and exhibit the type of bonds using different substances. (eg. beeds, seeds)
(Electronegativity values: P=3.44, Q=3.16, R=1.31, S=2.58)
1. P,R
2. P,S
3. Q, R?

Text Solution

Verified by Experts

1. P, R = Difference in their electronegativity value (3.44-1.31)=2.13, ionic bond
2. P,S = Difference in their electronegativity value(3.44-2.5) = 0.86, covalent bond
3. Q,R = Difference in their electronegativity value (3.16-1.31)= 1.85, ionic bond
