poor conductors of electricity and heat when solid
Good conductors of electricity when molten
Many are water soluble
High melting points
High boiling points
A compound containing only two chemical elements, linked by ionic bonds and able to release ions in water.
Example: sodium chloride (NaCl)
All ionic compounds are crystalline solids at room temperature. They typically have high melting points and are brittle/non-ductile.
Ionic compounds become electrolytes in water solutions.
True: Ionic compounds are composed of anions and cations False: They are composed of nonmetallic elements.
yes, but not all salts are binary ionic compounds
It is true of binary ionic compounds but not necessarily of compounds containing polyatomic ions.

True: Ionic compounds are composed of anions and cations False: They are composed of nonmetallic elements.

It is true of binary ionic compounds but not necessarily of compounds containing polyatomic ions.
Ionic compounds do not require the presence of a metal, for example ammonium chloride is ionic and does not contain a metallic element. What is true is that the majority of ionic compounds involve at least one metal.
True
True

TRUE
I classify that as an overstatement. It is true that a great many ionic compounds are highly soluble in water, but not all of them.
Yes. All chemical compounds, ionic and covalent, contain 2 or more elements.
true
Yes it does.
