This is an old term used by Werner (1866-1919) in a description of the bonding of transition metal complexes. As an example in the complex CoCl3.6NH3 he proposed that Co bonded to the 6 ammonia molecules using its "auxiliary" or secondary valence and to the chloride by its main valence. Up until then there was debate as to how Co with a valency of could attach 6 NH3 in addition to bonding with 3 Cl.
This essentially the model that is now accepted and we term NH3 as ligands and the Co(NH3)63+ (now known to be octahedral) , as a complex of Co3+
Werner is sometimes called the father of coordination chemistry.

How many valence electrons are in C2?
C is 4*2 H is 1*2 For a total of 10 valence electrons
In pi3 total of valence electron?
No such thing as pi3, but if you mean PI3, then there are 5 valence electron in P, and each I has 7 valence electrons for a total of 5 + 7 + 7 + 7 = 26 valence electrons.
What does an oxidation number of -1 mean?
A valence of -1, a monovalent anion as halogens ions.
Elements in the same group have the same what?
If you mean group then your referring to the columns of the periodic table. They will all have the same number of valence electrons and similar chemical and sometimes physical properties.
What are the electrons in the outer shell of an atom called?
valence electrons

Is go become an auxiliary using auxiliary in the right form?
Auxiliary has several meanings. This is one correct usage - if you mean "Become an assistant to someone or something."
What does it mean when someone has an auxiliary function?
An auxiliary function is an extra function. You might have a main or primary function, such as teaching math, and an auxiliary function such as coaching basketball.
What do you mean by valence shell and valence electrons?
The valence electrons are involved in the chemical bonding of atoms in a molecule.

How many valence electrons are in C2?
C is 4*2 H is 1*2 For a total of 10 valence electrons
In pi3 total of valence electron?
No such thing as pi3, but if you mean PI3, then there are 5 valence electron in P, and each I has 7 valence electrons for a total of 5 + 7 + 7 + 7 = 26 valence electrons.
How many core electrons in an Iodine atom?
I am not positive what you mean by "core electrons" but: 57 (total) 7 (valence, outermost) 50 (non-valence, everyone but valence)
Why are the valence electrons located in an atom?
If you mean "where are the valence electrons" then they are flying around the outside of the atom.If you mean "why" then I don't know. they're just there to be the outermost set of electrons.
