If one substance is losing electrons (where it is gaining charge, or oxidizing), we must assume those electrons are going to another substance in the reaction, which will cause the charge to go down, or reduce. This type of equation is called a Redox (reduction-oxidation) reaction.
An oxidation reaction occurs when a chemical substance loses electrons to another substance. The substance gaining electrons undergoes a reduction reaction. These types of reactions are called oxidation-reduction reactions, or redox reactions.
Oxidation reactions occur when the oxidation state of an atom increases, such as occurs when an atom loses electron(s). A reduction reaction occurs when the oxidation state of an atom is decreased, such as occurs when an atom gains electrons. Not all redox reactions result in an actual gain or loss of electrons, such as in reactions involving covalent bonds. However, they always involve the increase or decrease of oxidation state.
Redox, but if the other didn't get the elect,

Thousand of thousands chemicals can be combined by chemical reactions.

A chemical substance is a material with a specific chemical compound. A common example of a chemical substance is pure water; it has the same properties and the same ratioof hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Some typical chemical substances are diamond, gold, salt (sodium chloride) and sugar (sucrose). Generally, chemical substances exist as a solid, liquid, or gas, and may change between these phases of matter with changes intemperature or pressure. Chemical reactions convert one chemical substance into another. Forms of energy, such as light and heat, are not considered to be matter, and thus they are not "substances" in this regard.
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.
No and element cannot be broken down or changed into another substance through a chemical change. The number of protons in the nucleus of an atom determines the identity of the substance. But, a chemical change involves only the atoms electrons. -SmartyPants94
When one substance or combination of substances undergo change to become another substance or substances
That reaction is called Ionic bonding. Hope I helped, 2000AD
endothermic and exothermic reactions
The ability to combine with another substance is a chemical change. This is because once the substance is made it can not be taken out.
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
these are chemicals that speed up chemical reactions?
Thousand of thousands chemicals can be combined by chemical reactions.
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
A standard chemical reaction always and only involves a change in the electron configuration of the atom (either the number of electrons or their energy configuration).If the nucleus is affected (either the number of protons or electrons), then it is designated as a nuclear reaction, and this is quite different.
by the number of electrons in its outermost shell
When an element reacts with another element, they form a compound. How a compound is formed has to do with the number of valence electrons. The valence electrons are the electrons which are held in the outer most energy level.
