Essential Chemistry for IGCSE - Formulae And Equations (Section 5 - No. 3)
Which of the following statements are correct regarding ionic compounds?
They are formed by the transfer of electrons.
They typically have high melting and boiling points.
They are composed of molecules.
They conduct electricity in the solid state.
