Boron
Generally third A group elements in the periodic table exhibit +3 oxidation state but Boron exhibit negative oxidation state also . The stable oxidation state of Tl is +1. It exhibit +3 also but +1 is more stable than +3. RGUKT IIIT NUZVID N091528
fluorine
In a compound the sum of oxidation states of the elements contained is zero.E1 + E2 + ... = 0If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
The element oxidation state is a chemical property: it is zero for all elements.
A pure metal has the oxidation state zero.

The group I-A and III-A group have both positive and negative oxidation state . In I-A group H (hydrogen) has negative oxidation state and positive oxidation state.In III-A group B(boron) performs both positive and negative oxidation states. RGUKT IIIT NUZVID: N091528
Elements in group 2 mostly takes the oxidation number +II.
+2
The most common oxidation state of -2 would be Oxygen.
Group 1 elements are the most electropositive in nature and have only 1 valence electron. So, they always show the oxidation state of +1.
all the pure elements have zero oxidation state.....
OXYGEN because it has only one oxidation state of -2, all the other elements in the group have multiple oxidation states.
because the electronegativeties of these elements are low thy don't have much tendency to form negative ions
negative numbers --go to the discussion spot and it will help you. :)
fluorine
all the pure elements have zero oxidation state.....
