Cerium is stable in 4 oxidation state?
Cerium(III) is more stable
What is the result of this oxidation?
When a substance is oxidized, it loses electrons. Thus, its oxidation state becomes more positive.
Does oxygen atoms become more stable or less stable when oxygen forms compounds?
Oxygen becomes more stable when it forms compounds.
Does an element that loses electrons when bonding with other atoms have a negative oxidation number?
No. The lower (or 'more negative') the oxidation number, the more electrons the atom has. This is because the oxidation number is a measure of the charge on that molecule and, since electrons have negative charge, more of them give a more negative oxidation number. So if an atom loses electrons during bonding, it has lost some of its negative charge - giving it a more positive oxidation number.
Why Mohr's salt is considered a primary standard?
The Mohr salt is more stable to oxidation of Fe2+ to Fe3+.

Can Chlorine oxidation number ever be negative two?
No, that is not possible for Chlorine. Some elements have more than one oxidation number, such as Iron, Mercury, Copper, etc, but Chlorine only wants to gain one electron. If it had a -2 charge, it would not be stable, so that would never happen.
What do the oxidation number of 2 and -2 imply?
An oxidation number of 2 means the ion has two more protons than electrons. An oxidation number of -2 means the ion has two more electrons than protons.
When naming a transition metal that has more than one oxidation number the numeric value of the oxidation number is indicated by a?
Roman Numeral
How does a succession occur after a forest fire?
The ecosystem becomes more stable and diverse
What describe how succession changes the ecosystem?
The ecosystem becomes more stable and diverse.
Can an element have more than one oxidation number?
Of course they can have.Many elements have several oxidation numbers.
Copper oxidation number?
It depends on the compound. +1 and +2 are the more common ones (as in Cu2I2 and CuI2 respectively). In elemental form, its oxidation number is zero.
