Hydrogen has -1 and +1 oxidation numbers.
Other elements have +1 only
the oxidation number of elements in group two is -2
Group 1 elements have +1 oxidation number (except for hydrogen) All group 2 elements have +2 oxidation number Fluoride ion always has -1
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.
+2 for group 2 elements
Because there in group 2
Because there in group 2
Group 1 elements have +1 oxidation number (except for hydrogen) All group 2 elements have +2 oxidation number Fluoride ion always has -1
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.
+2 for group 2 elements
Because there in group 2
Because there in group 2
Elements in group 2 mostly takes the oxidation number +II.
Generally for group 16 elements, like oxygen, sulphur, selenium.
The most common oxidation state of -2 would be Oxygen.
The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
They share the same number of electrons (=2) in the valence shell: they have the same oxidation state of +2
Group 17 elements are also known as halogens. Atomic halogens have 0 as their oxidation number. They tend to accept an electron from another element to become stable: the new oxidation state would be -1.
Predominantly those in wide form periodic table column 16, especially oxygen and sulfur.
