What is the oxidation number for group 2 elements?
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Elements that have a single oxidation number?
Group 1 elements have +1 oxidation number (except for hydrogen) All group 2 elements have +2 oxidation number Fluoride ion always has -1
What is the oxidation number of group 1 elements?
+1 only for all elements (except for hydrogen) hydrogen can have +1 and -1 as their oxidation numbers.
Why do elements in group 2 have an oxidation number of -1?
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.
What are the oxidation numbers for the elements in Na2S2O3?
Na2S2O3 oxidation number
Elements with an oxidation number of 1 include what elements?

Why do elements in group 2 have an oxidation number of -1?
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.
Why do elements in group one have plus 1 oxidation number?
Because they have one valence electrons, and if they lose this electron they attain an oxidation number of +1
What are the oxidation numbers for the elements in Na2S2O3?
Na2S2O3 oxidation number
What is the oxidation number to each element FeCl3?
It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
What is the oxidation numbers of alkaline metals?
The question should be either 'alkali metals' or 'alkaline earth metals'. For alkali metals or group 1 elements, the oxidation number is +1 (note. hyddrogen can have +1 and -1). For alkaline earth metals, the oxidation number is +2 In addition all these elements will have an oxidation number of 0 in their elemental form
What is the oxidation number for F2?
The oxidation number of F, or Fluorine, is F-1. Since it is in the seventh group on the periodic table, it has seven valence electrons. It needs to get eight valence electrons to be stable, so it will gain one electron.
What group of elements can have more then 1 oxidation number?
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.
Oxidation number for first 20 elements?
H -->+1 He --> 0 Be --> B
