Which of the following statements concerning ionic compounds is true? Which of the following statements concerning ionic compounds is true? The chemical formula for an ionic compound must show a nonzero net charge. Essentially all ionic compounds are solids at room temperature and pressure. Ionic compounds contain the same number of positive ions as negative ions. Ionic compounds do not contain any covalent bonds.

The compounds which are made up of ions are known as ionic compounds.
a) The chemical formula for an ionic compound must show a non zero net charge:
=> Incorrect,
because ionic compound consist of equal number of positive and negative ions,so the overall charge of an ionic compound is zero.
For example, sodium chloride (NaCl) is an ionic compound which is made up of equal number of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-).
b) Essentially all ionic compounds are solids at room temperature and pressure.
=> Correct,
we know ionic compounds are formed by the bonding between positive and negative ions have Strong Electrostatic Force, because of strong electrostatic force between the ions force ionic compound to be in a solid state in crystal lattices.
