Aluminum (Al) is in group 3A of the Periodic Table, and as such it has 3 valence electrons, which it very much wants to lose. When losing these 3 valence electrons, it gets a 3+ charge, and this is the combining "power", or the oxidation state (3+).
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
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.
To calculate the oxidation state of fluorine in O2F2, first draw a diagram of the molecule: F-O-O-F Determine the most electronegative atom(s), which are fluorines -- the most electronegative atom there is. Being in the group 7A, a fluoride ion would gain an electron to a -1 charge, so each has an oxidation number of -1. The oxygens, therefore, have an oxidation number of +1 each.
the number of electrons the element needs to lose or gain to have a full valence shell
The oxidation state of nitrogen in NaNO2 is +3. This is because sodium is typically in the +1 oxidation state, and oxygen is in the -2 oxidation state. By assigning x to the oxidation state of nitrogen, the sum of the oxidation states in NaNO2 equals zero. Solving for x gives nitrogen an oxidation state of +3.
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.
The most common are 0 and 3+.
+3
+3 in its compounds
the most common oxidation state of chlorine is -1.
The oxidation state of chloride (Cl) is -1. As a halogen, chloride is usually found with an oxidation state of -1 in most compounds.
The oxidation state is 1.
The oxidation state of tungsten in its most stable compound is 6.
The oxidation state for oxygen in the oxide ion (O2-) is -2. Oxygen typically has an oxidation state of -2 in most of its compounds.
Mercury's most common oxidation state is +2
Most common oxidation state of Gold is 0, because its most common form is its elementary form.
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.
