1. Ions

2. WHAT is an ion? An ion is any atom or molecule with net charge, either positive or negative.

3. How ions are formed? Ions are formed when a neutral atom or molecule gains or loses one or more electrons, resulting in an unequal number of protons and electrons and an overall electric charge. Ionization is the process where an atom or molecule becomes an ion by gaining or losing electrons, resulting in a net electric charge.

4. Two types of ions

5. What is a cation? A cation is an  atom  or  molecule  positively charged due to the loss of one or more electrons. This positive charge arises because the number of protons in the nucleus exceeds the number of  electrons  in the outer shell. Cations are common in  chemical reactions  where atoms tend to lose electrons to achieve stability. Elements that form cations are primarily  metals  because they tend to lose electrons to achieve a stable electron configuration, resulting in a positively charge ion. Electropositivity is the tendency of an atom or element to lose electrons and form a positively charged ion (cation).

6. What is an anion? An anion is a negatively charged ion formed when an atom or molecule gains one or more electrons. Because electrons carry a negative charge, the gain of extra electrons gives the atom more electrons than protons, resulting in a net negative charge Elements that form cations are primarily non- metals  because they tend to gain electrons to achieve a stable electron configuration, resulting in a negatively charge ion. Electronegativity is an atom's ability to attract shared electrons in a bond, typically seen in non-metals

7. How does the periodic table help us what type of ion is formed by a given atom?

8. (or oxidation state) is a hypothetical charge assigned to an atom in a compound. Indicating the degree to which it has lost or gained electrons, with positive numbers signifying electron loss and negative numbers indicating electron gain. Oxidation number

9. A positive oxidation number indicates the atom has lost electrons.  A negative oxidation number indicates the atom has gained electrons.  Types of oxidation number

10. Naming the cations and anion

11. A CATION is named by simply adding the term “ion” or “cation” after the name of parent atom.

12. Am Anion is named by the root name and simply changing the end with the suffix “ide”.

13. Nomenclature of molecular compounds

14. C hemical N omenclature   is the systematic set of rules and procedures for naming chemical compounds and substances. This standardized system, primarily governed by the International Union of Pure and Applied Chemistry (IUPAC), ensures that each compound has a unique, unambiguous name, allowing scientists worldwide to communicate and understand chemical structures and compositions

15. Naming a binary ionic compound

16. Crisscross method is a method of finding out the chemical formula of a metal and non metal that combine to form an ionic bond.

17. Example: Sodium Chloride Magnesium Chloride

18. In terms of transition metals

19. Example: Ferric Oxide or Iron(III) oxide

20. Naming a binary covalent compound
