1) Materials that have high binding energy have high/low strength and melting temperature. Materials with ionic bonding have a particularly large/small binding energy due to the 2) large/small electronegativity difference between the ions. Metals have relatively higher/lower binding energies as the electronegativities of the atoms are similar. 3) A low-activation energy and rapid diffusion rate are obtained for (1) interstitial/vacancy diffusion, (2) crystal structures with a higher/smaller packing factor, and (3) materials with a high/low melting temperature or weak atomic bonding.

Q2 -Circle the correct word in the following sentence( 1) Materials that have high binding energy have high/low strength and melting temperature. Materials with ionic bonding have a particularly large/small binding energy due to the 2) large/small electronegativity difference between the ions. Metals have relatively higher/lower binding energies as the electronegativities of the atoms are similar. 3) A low-activation energy and rapid diffusion rate are obtained for (1) interstitial/vacancy diffusion, (2) crystal structures with a higher/smaller packing factor, and (3) materials with a high/low melting temperature or weak atomic bonding. 4) Smaller grain size higher/lower structural disorder. 5) Smaller grain size harder/lower to move dislocations across grain boundaries due to more barriers for slip. 6) More barrier for slip higher/lower material strength.
