The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
What else can I help you with?
Elements that have a single oxidation number?
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.
What are the elements with fixed oxidation number?
Elements with fixed oxidation numbers include alkali metals (group 1 elements) which have a +1 oxidation state, alkaline earth metals (group 2 elements) which have a +2 oxidation state, and nonmetals in group 17 (halogens) which have a -1 oxidation state in compounds.
What is the oxidation number for all elements in this group?
Group 1 elements have an oxidation number of +1.
Oxidation number of groups in periodic table?
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 with an oxidation number of 1 include what?
The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
What is the oxidation number of pure elements?
all the pure elements have zero oxidation state.....
Elements with an oxidation number of 2 include which of the following?
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium all have an oxidation state of plus 2.
What is the oxidation number for group 2 elements?
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Why do elements with a positive oxidation number easily combine with those having a negative oxidation number?
Elements with positive oxidation number easily combined with those having a negative oxidation number because opposite oxidation number attracts each other.
What what elements most common oxidation state is 2?
Elements in group 2 mostly takes the oxidation number +II.
What elements can have variable oxidation numbers are known as known as what group of elements?
Most elements can have more than one oxidation number, but I think you are looking for the transition elements in groups 3 - 12.
Why do elements with positive oxidation number easily combined with those having a negative oxidation number?
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.
