Because molecule was originally defined as a cluster of two or more atoms held together by a covalent bond. So it's not accurate if we say it molecules of ionic compounds. The true sentence is polyatomic ions.

∙ 10y agoIonic bonds are electrostatic in nature and the electric field around an ion is spherical, the force of attraction is "non-directional" - this causes large scale lattice structures to form. Ions pull in other ions from all directions. Covalent bonds are directional.

∙ 9y agoMolecular formulas are not practical for ionic compounds because they do not have any molecules. A formula like the empirical formula must be used instead since they have ions.

What are substances that are extended structures made up of billions of tightly packed atoms and molecules?
Just about anything you can see with your naked eye is made up of billions of molecules.
What is a substance made of 2 or more different molecules?
Substances made up of two or more different molecules are called compounds. An Ionic compound is made up of a non metal and a metal while a covalent compound is made up of a non metal and another non metal. There is no such thing as a compound composed of a metal and a metal.
What molecules made up of two identical atoms that share the electrons equally?
ionic compund
Why do you think substances that are made up pf molecules do not normally conduct electricity?
because they do not have delocalized electrons
How are elements atoms molecules chemical bonds compounds mixtures and substances related?
Elements and atoms are mainly the same. Molecules are made up of atoms and chemical bonds are bonds that combine the atoms together to make molecules. Compounds are just about the same as molecules only are made up of molecules like how molecules are made of atoms. Substances can relate to anything, and mixtures are many compounds and molecules mixed together.
What term describes the units that make up substances formed by ionic bonding?
The term that describes the units that make up substances formed by ionic bonding is ions. This may also be referred to as ionic bonds.
Is CaCl2 made up of molecules?
No. It is an ionic compound. It is made of ions.
What are molecules made up of?
Molecules are substances consisting two or more atoms.
Are molecules covalent bonds or ions?
Molecules are made up of covalent bonds; however, search "ionic molecules" for more info.
What are the differences between molecular bonds and ionic bonds?
Molecular substances have a lower melting and boiling point than Ionic. Also, molecular substances can be two non metals joined together where as Ionic it is a metal and nonmetal. Molecular substances have covalent bonds and Ionic have Ionic bonds.
What is matter made up of two or more substances known as?
Compounds / molecules
Is a mineral made up of molecules?
Yes. Everything is. And molecules are made up of atoms. And atoms are made up of electrons, neutrons, protons. What those are made up of is still anyone's guess.
What are substances that are extended structures made up of billions of tightly packed atoms and molecules?
Just about anything you can see with your naked eye is made up of billions of molecules.
Which high molecular weight substances are made up of repeating units of these molecules?
starch and cellulose
What is a substance made of 2 or more different molecules?
