oxidation numbers and types of lons
Answers
Answer:
xidation number in simple terms can be described as the number that is allocated to elements in a chemical combination. The oxidation number is basically the count of electrons that atoms in a molecule can share, lose or gain while forming chemical bonds with other atoms of a different element.
Oxidation number is also referred to as oxidation state. However, sometimes these terms can have a different meaning depending on whether we are considering the electronegativity of the atoms or not. The oxidation number term is used frequently in coordination chemistry.

In general, oxidation state or number helps us describe the transfer of electrons. However, students have to note that it is different from a formal charge which determines the arrangement of atoms. The oxidation number/state is also used to determine the changes that occur in redox reactions. Meanwhile, it is quite similar to valence electrons.
Answer:
★ What are Oxidation numbers?
→ Oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
OR,
The oxidation number of an atom is the charge that atom would have if the compound was composed of ions.
- The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element.
- The oxidation number of simple ions is equal to the charge on the ion.
• What are the different types of Ions?
→ There are specialized types of ions.Mainly there are two types of ions ( Anions and Cations ). Anions have more electrons than protons and so have a net negative charge. Cations have more protons than electrons and so have a net positive charge. Zwitterions are neutral and have both positive and negative charges at different locations throughout the molecule.
