due to participation of ns and n-1d electrons in chemical bonding
Group 1 elements have an oxidation number of +1, group 2 elements have an oxidation number of +2, group 17 elements have an oxidation number of -1, and group 18 elements (noble gases) have zero oxidation number since they are chemically unreactive.
Elements that have a single oxidation number include group 1 elements (e.g. sodium, potassium) which have an oxidation number of +1, and group 2 elements (e.g. magnesium, calcium) which have an oxidation number of +2.
Group 1 elements have an oxidation number of +1.
The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.
all the pure elements have zero oxidation state.....
The maximum oxidation number is theoretically equal to the number of valence electrons. For example the oxidation number of chlorine among different compounds can vary from -1 to +7. An exception for this is fluorine, which only have -1 and 0 as its oxidation numbers.
Predominantly, the transition elements, but also hydrogen, nitrogen, and oxygen. Actually all elements that have reactions can have more than one oxidation number in the sense that their oxidation number is 0 when they are in pure form and usually is some other value when they are in compounds.
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.
all the pure elements have zero oxidation state.....
The oxidation number is not specifically listed on the periodic table. Oxidation numbers are assigned based on rules and guidelines that depend on the chemical properties and bonding of each element. Different elements can have multiple oxidation states, which can vary depending on the compound or molecule in which they are found.
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
