Why did the word oxidation come to be applied to reactions in which a substance loses electrons?

is it because during oxidation, the exchange of ions occur.................tried my best.....m trying to answer my own question...:)

How is a conducting substance different from an insulating substance?
A conductor has more free electrons at the outer shell (valence) of its atoms. These free electrons move when an electric current is applied across the substance. Insulators, on the other hand, do not have as many free electrons and will take a stronger amount of energy for it to conduct the flow of electrons. In the real world, there are very few real insulators since lightning can flow across anything if the right circumstance exist.
How many valence electrons does thulium?
Thulium has an electronic configuration of [Xe] 4f136s2 You could count either 2 or 15. The concept of valence electrons is almost meaningless when applied to the lanthanides. Thulium is a typical member of these and has one common oxidation state, +3
Does iodine rust?
No, rusting is a term that is applied to the oxidation of metals, especially iron. Iodine is a nonmetal that can cause oxidation.
Which part of an atom plays a major role in chemical reactions?
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!
What are two characteristics of combustion reactions?
Combustion is the description of the reaction that results when a substance burns when heat is applied fast enough. Usually combustion also cause a rapid expansion of gasses from the reaction.
What is the oxidation number of nh2 oh?
Ox(N)= -3
What is the difference between of applied load and reactions?
The applied load refers to the load which acts on a structure at a given location or series of locations. The reaction is that which balances the applied load at the specific boundary (reaction) loactions. The sum of the applied load is equal to the reactions in the axis of application. For equilibrium, the sum of all forces and monemts are zero, so reactions may contain moment terrms under applied load, even if the applied laod has no applied moment.
Why electron freely in a metal?
The term conductor is generally applied to a substance or material that has a lot of free electrons in it. The name conductor is applied because the free electrons are already there. A material does not have free electrons because it is a conductor, but is a conductor because it has a lot of free electrons. That said, let's look at what's going on. These free electrons have energies that permit them to "wander" through the conductor; they're not "locked into" the structure of the material. And when a voltage (potential difference) is applied, current flows through the conductor because the free electrons are moving. They're made to move by the applied voltage. If we take the case of a wire in a circuit, the wire is a conductor. This wire, say a copper one, has many free electrons in it, and when we apply a voltage, electrons move. The voltage forces electrons into one end of the wire, and the free electrons "shift over" and electrons emerge from the other end of the wire. This movement of free electrons in response to an applied voltage through an conductor is the essence of current flow in that conductor.
How many electrons and protons does thulium have?
Thulium has an electronic configuration of [Xe] 4f136s2 You could count either 2 or 15. The concept of valence electrons is almost meaningless when applied to the lanthanides. Thulium is a typical member of these and has one common oxidation state, +3
What is the oxidation number of carbon in propane?
This value is conventionally considered to be +4, although "oxidation number" is preferably not applied to covalent compounds and substituted by "formal charge".
What are good insulaters?
Good Insulator are those substance which has almost no free electrons to move freely and thus, cannot conduct electricity. When EMF (Electro motive force) is applied along the length of the insulator, high resistance of the insulator causes no motion of the electrons due to which the electrons cannot flow.
