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.
What else can I help you with?
What has 5 electrons in its outer shell?
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
How many valance electrons are in iodine?
Iodine has 7 valance electrons
Valencies of all elements?
The valency of an element refers to the combining power of a given element. The valencies of all the elements is contained in the table of valencies. The valencies of the elements can be obtained by looking at the groups in the periodic table.
What is an oxidation number example?
An example of an oxidation number is in the molecule HCl, where hydrogen has an oxidation number of +1 and chlorine has an oxidation number of -1. The sum of the oxidation numbers in a neutral compound is always zero.
How do valence numbers help determine the oxidation number?
oxidation number is defined as a positive or negative number corresponding to the charge that an atom in a molecule or ion would have if the electron pairs belonged entirely to the more electronegative atom. in this case, they're talking about 'valance electrons'. An example would be...fluorine has 7 valance electrons. when bonded with another element, it would in almost all of the cases want to gain 1 more electron to have a full valance shell of 8 electrons. Therefore, it would become F -1 As a result, fluorine's oxidation number becomes -1, the same as its CHARGE when bonded to ANOTHER element (NOT ITSELF) when fluorine bonds to itself to become Fluorine gas, its oxidation number is zero. that goes for all ....elements which bond with itself to form a diatomic molecule (oxygen gas, hydrogen gas, etc) --gh ---
How many elements within a row different?
They have different numbers of valance electrons
How do you find oxidation number in an atom?
By looking to see how mwny valance electrons you have.
What elements have two valance electrons?
alkaline earth metals
How many valance electrons do most elements need to have a stable electron configuration?
8 valance electron
What has 5 electrons in its outer shell?
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
How is the reactivity of elements related to valence electrons in atoms?
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
How can the number of valence electrons be determined from the periodic table?
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
