It is difficult to break the ionic bonds in a compound because of a. good conductivity between ions. b. small distance between the ions. c. strong attraction between ions. ionic compounds are solid at room temperature because they a. high melting points b. ion with similar charges c. no valence electrons

1) C. Strong attraction between ions.

2) A. High melting points

Explanation: Ionic compounds are formed by combination of positively charged ions called cations formed by less electronegative metals and negatively charged ions called anions formed by more electronegative nonmetals.

The cations and anions with opposite charges are bonded through  strong coloumbic forces and thus are difficult to break and have high melting points and thus exist as solids at room temperature.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

i would say b

explanation:

but i think i would need more information than that
