The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
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.
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.
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 oxidation numbers of +1 include elements in Group 1 of the periodic table, like hydrogen and sodium. Elements with oxidation numbers of -1 include elements in Group 17, like fluorine and chlorine.

+1 only for all elements (except for hydrogen) hydrogen can have +1 and -1 as their oxidation numbers.
The oxidation number for K in KCl is +1, as alkali metals (Group 1 elements) typically have a +1 oxidation state. For Cl in KCl, the oxidation number is -1, as halogens (Group 17 elements) typically have a -1 oxidation state when they form ionic compounds.
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
The oxidation number of Na in NaH is +1. In general, group 1 elements like sodium (Na) have an oxidation number of +1 in most compounds.
Elements with an oxidation number of 1 include alkali metals such as lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs). These elements typically lose one electron to achieve a stable electronic configuration.
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.
