Lons are defined as a) atoms that have lost or gained an electron and have a charge. b)atoms that are bonded to other atoms of the same elementc)neutral atomsd)nuclear atoms

Option A) Atoms have lost or gained an electron and have a charge

Explanation:

The result of a loss or gained electron can cause a large or lesser number of protons than the electrons, which causes a charge imbalance because protons have a positive charge and electrons have a negative charge.  If the number of protons or the number of electrons is unequal, then it means that the atom has a charge, and is an ion.  It is a cation if it lost an electron such that it has a positive charge and it is an anion if it gained an electron such that it has a negative charge.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
