poor conductors of electricity and heat when solid
Good conductors of electricity when molten
Many are water soluble
High melting points
High boiling points
The statement that all compounds have a composition of ionic compounds is false. Many compounds can be covalent in nature, where atoms share electrons instead of transferring them. On the other hand, it is true that compounds have a definite composition with fixed ratios of elements and compounds are formed by the bonding of two or more different elements.
True. Most salts are binary ionic compounds composed of a cation from a metallic element and an anion from a nonmetallic element.
True. Most salts are binary ionic compounds composed of a metal cation and a nonmetal anion.
True. Ionic compounds form between a metal and a nonmetal. The metal loses electrons to become a cation (positively charged ion), while the nonmetal gains these electrons to become an anion (negatively charged ion).
True. In an aqueous solution of ionic compounds, the positive and negative ions will attract each other due to their opposite charges, forming electrostatic bonds known as dipole attractions.

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
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.
True. Most salts are binary ionic compounds composed of a metal cation and a nonmetal anion.
True. Ionic compounds form between a metal and a nonmetal. The metal loses electrons to become a cation (positively charged ion), while the nonmetal gains these electrons to become an anion (negatively charged ion).
True. A common ion is an ion that is found in more than one ionic compound. These ions are shared among different compounds, which can affect their solubility and reactivity in solutions.

yes, but not all salts are binary ionic compounds
