What is the oxidation state of nitrogen in nano2 A +2 B +3 C +1 D +4? The answer is (3) +3. The Na ion usually has oxidation state of +1.
What metal is most easily oxidized?
The order of some common metals in the electromotive series, starting with the most easily oxidized, is: lithium, potassium, calcium, sodium, magnesium, aluminum, zinc, chromium, iron, cobalt, nickel, lead, hydrogen, copper, mercury, silver, platinum, and gold.
In which compound is the oxidation state of nitrogen 4?
Nitrate ion, oxidizing agent in acidic solution. +4 NO2 Nitrogen dioxide, a brown gas usually produced by the reaction of concentrated nitric acid with many metals.
What is the most likely oxidation state of nitrogen?
In compounds of nitrogen (where known), the most common oxidation numbers of nitrogen are: 5, 3, and -3.
What is nitrogen oxidation state?
Nitrogen has an oxidation state of +3 in the oxide N₂O₃ (a dark blue liquid with acidic properties) and nitrous acid HNO₂.
How do you tell which element is most easily oxidized?
Answer: Lithium
Easily oxidized elements readily release electrons. The loss of an electron allows these elements to form a stable valence electron configuration. In the context of this question, lithium is the most willing to release an electron, so it is the most easily oxidized.
What is most likely to be oxidized?
Fluorine gas is one of the best oxidizing agents there are and it is at the top of the table with the biggest most positive standard potential (+2.87 V). Reducing Agents: At the other end, are reactions with negative standard potentials. This means that the desired path of the reaction is actually the reverse reaction.
Is silver easily oxidized?
Reactivity: redox. In general, the ions of very late transition metals — those towards the right-hand end of the transition metal block, such as copper, silver and gold — have high reduction potentials. In other words, their ions are easily reduced.
What is oxidation number of no?
Answer: The oxidation number of nitrogen is +2.
Why does nitrogen have an oxidation state of 5?
This is obtained by the excitement of electrons of the central atom to empty d orbital. Since, nitrogen has no d orbitals, it cannot undergo sp3d hybridization and thus cannot form pentahalides. In N2O5 , nitrogen exhibit +5 oxidation state.
Which oxidation state is not shown by nitrogen?
In this context, keep in mind that the oxidation state of elemental oxygen (O2) and nitrogen (N2) is defined as zero.
What is the common oxidation state of lanthanides?
All lanthanides show an oxidation state of +3. It also shows an oxidation state of +2 and +4 in complexes, but +3 is the most stable.
Is Nitrogens oxidation number always?
For example, in NO 3 – the nitrogen is assigned an oxidation number of +5 and each oxygen an oxidation number of –2.
…
| Element | Usual oxidation state | Exceptions |
|---|---|---|
| Hydrogen | Usually +1 | Metal hydrides (-1) (see below) |
| Fluorine | Always -1 | |
| Chlorine | usually -1 | Compounds with O or F (see below) |

Can nitrogen have +5 oxidation state?
Nitrogen exhibits +5 oxidation state in nitrogen pentoxide(N2O5).
How many oxidation states of nitrogen can be possible?
Nitrogen compounds, on the other hand, encompass oxidation states of nitrogen ranging from -3, as in ammonia and amines, to +5, as in nitric acid. The following table lists some of the known organic compounds of nitrogen, having different oxidation states of that element.
Which of the following is the easiest to oxidize?
Alkalis are easily oxidized.
Which element is most active?
Lithium is the most active element in the periodic table.
What metals are easily reduced?
In the table provided, the most easily reduced element is Li and the most easily oxidized is iron. This means that Li would be written as the reduction half-reaction when compared to any other element in this table.
What is the weakest oxidizing agent?
H2O2 H 2 O 2 is a weakest oxidising agent because it can act as a reducing agent also.
How do you know if something can be oxidized?
In order to determine what happens to which elements in a redox reaction, you must determine the oxidation numbers for each atom before and after the reaction. … If an atom’s oxidation number decreases in a reaction, it is reduced. If an atom’s oxidation number increases, it is oxidized.
Which is a stronger oxidizing agent Ag+ or Cu2+?
Cu2+ is a stronger oxidizing agent than Al. Therefore, Cu2+ can oxidize Al but not vice versa. The lower Ehalf-rection, the product gets oxidized easier and is a better reducing agent (anode).
What does oxidized silver look like?
The color of oxidized silver is superficial; Just the top layer of metal has turned the blackened color. Over time, even with the best of care, the oxidized finish will polish off and the true color of the silver will shine through.
What is the most common oxidation number of oxygen?
The most common oxidation state of oxygen is −2.
Can nitrogen show plus 5 oxidation state?
N cannot form compounds with +5 oxidation states as it has no d orbitals in its outermost shell. Hence it cannot expand its octet and it’s Maximum covalence is restricted to 4. But in HNO3 nitrogen has oxidation number +5. The ionisation enthalpy for NITROGEN to loose all 5 electrons is very large.
Do nitrogen Exhibit 5 oxidation state it does not form?
The p-Block Elements. Though nitrogen exhibits + 5 oxidation state it does not form pentahalide. … Nitrogen with n = 2 has s and p orbitals only. If does not have d orbitals to expand its valence shell.
