The Lewis formula refers to a diagram showing the distribution of electrones and in case of a molecule it also shows the bonds.
The structural formula on the other hand is a representation of the molecular structure that shows all the atoms that form the molecule, arranged in a three dimentional space,
In this case we have the hydrogen ion, which is the simpliest case we can have.
Hydrogen ion is the hydrogen atom possitively charged as it has lost his electron. Therefore the structural formula is simply the following:
The Lewis formula is also very simple as this ion has no electrons and has no bonding to other atoms:
It is <u>true</u> that ionic compounds are formed from atoms that have opposite charges.
<h3>What are ionic compounds?</h3>
Ionic compounds are chemical compounds made up of ions held together by electrostatic forces termed ionic bonding.
The ionic compound formed is neutrally charged but consists of positively charged ions called cations and negatively charged ions called anions.
For example, the sodium ions attract chloride ions and the chloride ion attracts sodium ions. The result is the formation of an ionic compound with cation Na+ and anion Cl– ions.
Therefore, it is true that an ionic compound is made up of positive and negative ions.
