Why noble gas show variable oxidation state?
because they are stable
why do alkali metals not show plus 2 oxidation state?
why do alkali metels not show +2 oxidation state
When does iron show the 4th oxidation state?
Never. iron shows either +2 or +3 oxidation state but in Fe3O4 its oxidation state is seems to +4 but it is actually mixture of one moles FeO and one mole Fe2O3 , (FeO.Fe2O3 = Fe3O4).
Name the metal that has highest oxidation?
Ruthenium and Osmium both show the oxidation state of +8, which is highest known for any single metal ion.
Why alkali metals do not show 2 oxidation state?
Because they have only one electron in their valency shell. The second oxidation state would require the atom to lose an electron from its penultimate shell which is full.

What is difference between lanthanide and actinide?
If you are talking about the elements then they are two different elements with different atomic no. and properties. On the other hand if you are talking about the 2 groups in the F block then there are 3 major differences: 1. Except for Promethium lanthanoids are not radioactive while all Actinoids are 2. Oxidation state is usually +3 for Lanthanoids and they also show +2 & +4 while Actinoides show +4,+5,+6,+7 Oxidation States 3. The magnetic property of Actinoids are more complex than Lanthanoids
When do halogens show 1 and -1 oxidation states?
When halogens bind to more electropositive elements (compared it itself), they show -1 oxidation state. When halogens bind to more electronegative elements (compared it itself), they show +1 oxidation state.
Why d block elements show variable oxidation state?
Due to the comparable energies of ns and the (n-1)d orbitals, the d-electrons also take part in the reactions.
Why Mn does not show an oxidation state 5 plus?
It is rarely, but manganese can show the valence 5+.
When does iron show the 4th oxidation state?
Never. iron shows either +2 or +3 oxidation state but in Fe3O4 its oxidation state is seems to +4 but it is actually mixture of one moles FeO and one mole Fe2O3 , (FeO.Fe2O3 = Fe3O4).
Family characteristic actinides have?
All are radioactive and all of them can show the oxidation state of +3
Name the metal that has highest oxidation?
Ruthenium and Osmium both show the oxidation state of +8, which is highest known for any single metal ion.
Why alkali metals do not show 2 oxidation state?
Because they have only one electron in their valency shell. The second oxidation state would require the atom to lose an electron from its penultimate shell which is full.
What do half reactions show?
They show the oxidation an reduction halves of a reaction
Why do transition metals have variable oxidation states?
Transition metals can move electrons between the outer shell and the d d orbital. For example, copper can either lose its 2 s electrons or move one of those s electrons into d orbital, which is one electron short of being full.
