Electronic configuration of scandium: [Ar]3d1.4s2.
In chemistry, the oxidation state is a number assigned to an element as an indicator of the degree of oxidation of an atom in a chemical compound."The charge an element would have if it were an ion "Oxidation state is the same as the oxidation number. It is an indicator of the degree of oxidation of an atom in a chemical compound.
Atomic number is not related to oxidation number. If you want to find the atomic number of a particular element, all you have to do is find it on the periodic table of elements.
the answer is -2.Related Information:The oxidation number of oxygen when it appears as an element is 0. The oxidation number in all compounds but peroxides is -2. The oxidation number of oxygen in peroxides is -1.
They must always occur in the same reaction; if one element or compound is oxidized, another one must be reduced.
The electron configuration of gallium is 1s22s22p63s23p64s23d104p1 The shorter version is [Ar]4s23d104p1
The chemical properties of any given element are the result of it electronic structure. The mass number is not related to the electronic structure because the mass includes neutrons, which not related to the electron structure (unlike protons). Any given element exists in more than one form (called isotopes) which have different numbers of neutrons, but the same electronic structure (and the same number of protons).
The position of an element in the periodic table is determined by it's atomic mass, so the amount of protons and neutrons in it's nucleus.
It indicates how many electrons are required to complete a full valence shell.
