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 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.
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
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.
The most likely oxidation state of an element is determined by the number of valence electrons it has. Elements tend to react in a way that allows them to achieve a full outer electron shell, often following the octet rule. This leads to the most common oxidation state for that element.
Mercury's most common oxidation state is +2
It indicates how many electrons are required to complete a full valence shell.
An element's most likely oxidation state is often related to its valence electrons because elements tend to gain or lose electrons to achieve a stable electron configuration. The number of valence electrons an element has can determine how many electrons it will gain or lose to reach a full or empty outer shell, resulting in a specific oxidation state.
the number of electrons the element needs to lose or gain to have a full valence shell
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.
An element's most likely oxidation state is often related to its number of valence electrons. The oxidation state is typically the charge an atom assumes when it forms ions, and it tends to be the same as the number of valence electrons the atom gains or loses to achieve a stable electron configuration.
the most common oxidation state of chlorine is -1.
