The highest oxidation state ever achieved by an element is +8. This oxidation state can be found in 3 elements: Osmium, Ruthenium and Xenon.
The synthetic element Hassium is also expected to have this oxidation state.
The lowest oxidation state possible for an element is -4
This is observed in Carbon, Silicon, Germanium, Tin and Lead
The highest oxidation state that is known to occur in a metallic ion is +8. This occurs in the formation of tetroxides with ruthenium, xenon, osmium, iridium, hassium, plutonium, and curium.
There are 3 elements which have the highest oxidation state of +8. They are Osmium, Ruthenium and Xenon
One of the alkaline earth metals (column 2 of a wide form Periodic Table) is most likely to have an oxidation state of +2. Oxygen and sulfur are most likely to have an oxidation state of -2.
the number of electrons the element needs to lose or gain to have a full valence shell
The most common oxidation state of -2 would be Oxygen.
2(IIA) Because The elements in Group 2 (IIA) are metals with a +2 oxidation state. Thus one atom of a Group 2 metal can combine with 2 atoms of chlorine (oxidation state = -1)
In one's initial studies of chemistry it is -1. However, don't forget that in chlorine itself the O.S. is zero.
Oxidation
the number of electrons the element needs to lose or gain to have a full valence shell
The number of electrons of the element needs to lose or gain to have a full valence shell (apex)
It indicates how many electrons are required to complete a full valence shell.
the most common oxidation state of chlorine is -1.
Mercury's most common oxidation state is +2
The highest oxidation state which can be achieved by any element is +8. After all experiments, this state is only found in Osmium, Ruthenium and Xenon. But the synthetic element Hassium is also expected to have this oxidation state.

oxygen
The most common oxidation state for chlorine is 1- (negative one).
This value is 3+.
