Cation: Are the atoms that lose an electron so they become Positive.
Anion: Are the atoms that gain an electron so they become Negative.

Gain or electron means reduction energy is not gained but given off during this and also when oxidation takes place the same thing thing happens' energy is released when a redox reaction takes place(ie both oxidation & reduction)
How many electrons are taken up by an oxidant in the 1st halfreaction (oxidant reaction),and how many electrons are given free by a reductant in the 2st halfreaction (reductant reaction)
Most atoms have the ability to lose electrons, given the conditions are favorable, e.g. in a chemical reaction, but the ones that loose their electrons easiest are the ones with only a few electrons in their outer shell, such as the alkali metals and alkaline earth metals which only have 1 and two electrons, respectively.
This reaction can be called "deoxidation" or "reduction".
How could a chemist find out how much mass is given off as gas during a chemical reaction

The VALENCE Shell. In any chemical reaction it is the electrons in the Valence Shell that do the reacting. Any inner shells of electrons do NOT take part in a chemical reaction.
Taken from Introduction To Corrosion Science by E. McCafferty Two notable things occur during a cathodic reaction. 1.) A given species undergoes reduction (there is a decrease in its oxidation number) 2.) A gain of electrons at the cathodic site (electrons are consumed by the reaction) An example of a cathodic reaction is: 2H+(aq) + 2e- ==> H2(g) This reaction however is just a half-cell reaction, which means it is usually coupled (happens along with) an anodic reaction.
An element that decreases its oxidation number in a chemical reaction is undergoing reduction. In the given reaction, the element that is reduced is the one that gains electrons and decreases its oxidation number.

In the given reaction, B2H6 reacts with 3 O2 to form B2O3 and 3 H2O. To balance the reaction, 12 electrons are transferred: 12 electrons are lost by the boron atoms in B2H6, and 12 electrons are gained by the oxygen atoms in O2 to form water molecules.
It is sign of chemical reaction because smell and heat is produced.
The given chemical equation represents a redox reaction, specifically a reduction-oxidation reaction. It involves the transfer of electrons between iron (Fe) and hydrogen (H) to form different compounds.
