How are cations anions monoatomic ions and polyatomic ions the same and different?
Cations are positive ions (Fe2+, NH4+).Anions are negative ions (Cl-, (SO4)2-).Fe2+ is a monoatomic ion and (NH4)+ is a polyatomic Ion (contain more than one element).
Do ions have more electrons than the atoms from which they were formed?
of course, ions are formed by loosing (cations) or gaining (anions) electrons. anions have more electrons than the atom from which it is formed.
What is an antifluorite?
An antifluorite is a type of crystal structure in which the cations and anions in a crystal lattice are arranged in a specific pattern. In an antifluorite structure, the anions occupy the positions that cations would normally occupy, and vice versa. This results in a reversed or "anti" arrangement compared to the more common structure of fluorite.
What do you get when the number of protons and electrons in your model is not equal?
Cations are formed if electrons are less. Anions are formed if electrons are more.
How are simple cations and anions named?
Simple metal cations take the name of the metal. Where there are more than one type of ion as is the case with iron, the lower charged ion ends in -ous and the higher charged in -ic. This convention is old, and doesn't cope with elements with more than two cations, but is in general use.Simple anions are the "root" of the element name ending in -ide.Examples of cationsK+, potassium, Na+ sodium, Mg2+ magnesium Fe2+ ferrous Fe3+ ferricHg2+ mercuric, Hg22+, mercurousExamples of anionsCl- chloride, Br- bromide O2- oxide, S2- sulfideN3-, nitride

What is a polyatamic ion?
A polyatomic ion is one that contains more than one atom. Many common anions are polyatomic, e.g. NO3-, SO42-, CO32-, PO43- Cations may be polyatomic, e.g NH4+, Hg22+
Why anions are removed after cations?
You're really going to need to provide more context for this. Anions and cations can't be separately "removed" from anything.
What is the definition of cations anions monatomic ions and polyatomic ions?
Cation: an atom who lost electrons.Anion: an atom who gain electrons.Monoatomic ion: ion formed from one element, as chloride Cl-.Polyatomic ion: ion formed from two or more elements, as (SO4)2-.
Why do some formulas of ionic compounds have more than two elements?
Ionic compounds are comprised of cations and anions. Cations are species with positive charges, and anions have negative charges. There are lots of simple ions (Ca2+ and Cl- are good examples). But it is possible for there to be "Polyatomic Ions", i.e. molecules that are arranged in such a way that they have more or less electrons than there are protons in the molecule, and therefore have an overall charge. So in a compound like NH4Cl, the cation is NH4 + and the anion is Cl-

What happens to an atom to form and ion?
The loss of one or more electrons forms a cation; some atoms gain one our more electrons in becoming anions. Both anions and cations are ions. Anions have a negative valence (charge), cations have a positive valence. Cations and anions attract one another to form compounds, substances consisting of two or more kinds of atoms. These compounds, dissolved in water, a polarized solvent, become solute and revert to ions. In such solution, the cations, having positive charges, are attracted to the negative poles of water molecules, and this arrangement enhances the solvency of the compound in water. Similarly, the anions, having negative charges, are attracted to the positive poles of the water molecules. In this way, a solution of the compound in water is formed.

What are the similarities of polyatomic ions and monatomic ions?
Anions and cations are ions of a single atom of a single element (i.e. Lithium+1, Fluorine-1, etc.). Polyatomic ions are charged particles composed of multiple atoms of different elements (i.e. Nitrate (NO3)-1, Ammonium (NH4)+1, etc.).
What are the type of ion?
* Anions are negatively charged ions. Anions are negatively charged because there are more electrons associated with them than there are protons in their nuclei. * Cations are positively charged ions. Cations are the opposite of anions, since cations have fewer electrons than protons. * Dianion: a dianion is a species which has two negative charges on it; for example, the aromatic dianion pentalene. * Radical ions: radical ions are ions that contain an odd number of electrons and are mostly very reactive and unstable.Source: Wikipedia
