Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Elements with positive oxidation numbers have excess electrons that they can share or transfer with elements having negative oxidation numbers that have electron deficiencies. This transfer or sharing of electrons allows the elements to achieve a more stable electron configuration, forming compounds through the formation of ionic or covalent bonds.
The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.
The oxidation number for group 2 elements is typically +2. These elements have 2 valence electrons that they can lose to form a 2+ cation.
First, determine which family it is in on the periodic table. The group number equals the number of valence electrons that it has. It needs to end up with eight valence electrons to have a full octet. So if it has seven valence electrons, it will gain one electron to be stable. On the other end of the table, it will lose electrons to be stable.
Because they have one valence electrons, and if they lose this electron they attain an oxidation number of +1
Positive oxidation numbers are assigned to elements that lose electrons in a compound, while negative oxidation numbers are assigned to elements that gain electrons. The oxidation number is determined by the number of electrons gained or lost in forming the compound. The sum of oxidation numbers in a compound is always zero for a neutral compound, or equal to the charge of the ion in an ionic compound.
The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.
Elements in the same group have similar chemical properties because they have the same number of valence electrons. This leads to similar reactivity and tendency to form compounds with the same oxidation number. The oxidation number is related to the number of electrons an atom gains, loses, or shares to reach a stable electron configuration.
The oxidation number of transition elements can vary because they have multiple oxidation states. Transition metals typically exhibit more than one oxidation state due to the presence of partially filled d orbitals, allowing them to lose a variable number of electrons. Common oxidation states for transition elements range from +1 to +7.
The oxidation number of an element is a measure of the number of electrons that an atom of that element has gained or lost to achieve a stable electron configuration. It is a value that is assigned to an element in a compound to help track the flow of electrons in chemical reactions. Oxidation numbers can be positive, negative, or zero, depending on whether the element has lost, gained, or shared electrons.
Group 3 elements typically have an oxidation state of +3. This is because they have 3 valence electrons that they can lose to form stable compounds.
