No.
No - we exhale to remove air that has a high content of carbon dioxide. Excess oxygen is not a problem when breathing - oxygen deficiency IS a problem.
An isotope has an excess of electrons. This causes the chemical to be negative and able to bond with other things.
A positively charge body is deficient in electrons (electrons are negatively charge, so a lack of them results in something being positively charged).
Because they have either excess or deficiency of electrons, due to which the charge on the atom is unbalanced as the no. of protons always remain same. Thus the ion is charged
That is true but not very - the excess of electrons at the negative terminal is small. The important thing is that if you place a load (radio set, light bulb etc.) on the battery the electrons flow through the load and this movement is supported by energy supplied by chemical action in the battery.
When a material has an excess of electrons, it has a negative charge. When it has a deficiency of electrons, it has a positive charge.
When a material has an excess of electrons, it has a negative charge. When it has a deficiency of electrons, it has a positive charge.

Negative ions have an excess of electrons while positive ions have a deficiency of electrons.

A positive charge is built up which then wants to find a path to ground. It can be either polarity. It just depends on how the charge is generated and what materials used to generate it.
Excess of nutrients causes eutrophication i.e. excessive growth of algae take place leading to oxygen deficiency.
A positively charge body is deficient in electrons (electrons are negatively charge, so a lack of them results in something being positively charged).
Because they have either excess or deficiency of electrons, due to which the charge on the atom is unbalanced as the no. of protons always remain same. Thus the ion is charged
dearth, deficiency
No (this is valid for neutral atoms); anions have excess electrons.
