Question

12 Juli Materials that can give up their few valence electrons to become positively charged ions Electronegativity Equilibrium Electropositivity O 13 Jgundo Metals have High thermal and high electrical conductivity Low thermal and low electrical conductivity High thermal and low electrical conductivity Low thermal and high electrical conductivity 14 JB Which of the following is a secondary bond Metallic bond Hydrogen bondo Covalent bondo Ionic bondo

Answer 1

12) The prgiving of valence electrons to be positively charged is called electropositivity.

Third option is correct

13) metals have high thermal and electrical conductivity

first option is correct.

14) Hydrogen bond is secondary bonds between Hybdrogen and usually Oxygen atom.

So second option is correct.
