Why the elements of group 6a other than oxygen show more thentwo oxidation states?

As oxygen is located in the second period, it has only s and p subshells available. As it has already six electrons, it can gain only two electrons. That means two bonds. Other elements in the same group have d subshell available as well, and it means that they can form more than two bonds.

Except oxygen, the other members of group VIA show more than two oxidation states because they have empty d orbitals. They show oxidation states +2,+4 and +6, for examples, SC lĀ², SCl4, SCl6. +2 oxidation state is shown due to 2 unpaired electrons in the p_orbitals. +4 oxidation state is shown when 1 electron from "p" orbital os promoted to the next vacant d orbital; while +6 oxidation state is shown when one electron from p orbital and one electron from s orbital are promoted to the vacant d orbital.

How is an unknown oxidation state of an element within a compound determined?
It is determined from known oxidation states of other elements.
Which elements are most like sulfur?
From the Periodic Table, in Group 6. The other elements like sulphur are, Oxygen and selenium. All three are non metals, and have variable oxidation states. The there is the metalloid - Tellurium Finally, two metals, both radio -active, Polonium and Livermorium.
What is the oxidation state of Sodium Nitrate?
Sodium Oxide, or NaOH, has no oxidation state. It has a charge, which is zero. The elements that make up NaOH, however, do have oxidation states. The oxidation state of sodium (Na) is +1, and it will forever be +1 because it is impossible for it to be anything else, no matter what situation. The same applies for Hydrogen. Oxygen has an oxidation state of -2, and almost always will have an oxidation state of -2. There is one notable exception: H2O2. In this case, since the total charge of the compound is neutral and the oxidation state of Hydrogen must be +1 and, seeing as there are two hydrogens, bringing the overall charge up to 2, the oxidation state of oxygen must be -1. If it was -2, then the molecule would have an overall charge of -2.
What is the oxidation state of group 13?
Group 16 on the periodic table has elements that form a -2 charge when they bond ionically with metals. This group contains the very common elements oxygen and sulfur. They are usually referred to simply as group 16, group 6A, the "oxygen group," or by their old-fashioned name, the chalcogens.
What are the oxidation states of the atoms in a diatomic gas?
the oxidation states are always 0 for both atoms
What is the oxidation number of iodate?
Oxidation states of elements in Iodate anion: Iodine = +5 Oxygen = -2
Which of these elements become cations with positive oxidation states Calcium Oxygen Fluorine Magnesium?
Ca & Mg
Whose most common oxidation state is -2?
Oxygen is the element whose most common oxidation state is -2. In fact, it only shows oxidation states of +2,+1 in compounds OF2, O2F2. It is because oxygen is the second most electronegative element behind Fluorine.
Are atoms of group 16 elements more likely to gain or lose electrons?
OXYGEN because it has only one oxidation state of -2, all the other elements in the group have multiple oxidation states.
What is the oxidation states of the elements in FClO4?
FClO4 is the name of Fluorine perchlorate.Here Chlorine is in +7 oxidation state, Fluorine is in -1 oxidation state, 3 atoms of Oxygen (that are double bonded to Chlorine) are in -2 oxidation state, and the forth Oxygen atom (which is connected to Fluorine and Chlorine) is in 0 oxidation state.So, total charge = 7(of Chlorine) -1(of Fluorine) -(2 * 3)(of 3 Oxygen) +0(of Fourth Oxygen) = 0
How is an unknown oxidation state of an element within a compoud determined?
In a compound the sum of oxidation states of the elements contained is zero.E1 + E2 + ... = 0If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
What are the oxidation numbers of magnesium in magnesium dichromate?
In compounds, magnesium has a +2 oxidation state; in most but not quite all compounds, oxygen has a -2 oxidation state. In peroxides, oxygen has a -1 oxidation state. In oxygen fluorides, oxygen has positive oxidation states.
How is an unknown oxidation state of an element within a compound?
It is determined from known oxidation states of other elements.
What is the oxidation number of Pb3O4?
Pb3O4 contains oxygen in the 2- oxidation state. and lead in the 2+ and 4+ oxidation states.
How is an unknown oxidation state of an element within a compound determined?
It is determined from known oxidation states of other elements.
What is the oxidation state of oxygen in H2O2?
O = -2 oxidation state H = +1 oxidation state
When does iodine have an oxidation state of plus 3?
+/- 1 (5,7) are the listed oxidation states, but many of these elements that have many electron shells can reach deep into their valance shells for greater oxidation states due to a possibility of electron shielding.
