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.

Very many elements do. In atomic number order, they are:
Hydrogen, Carbon, Nitrogen, Silicon, Phosphorus, Sulphur, Chlorine, Manganese, Iron, Cobalt, Arsenic, Selenium, Bromine, Ruthenium, Antimony, Tellurium, Iodine, Rhenium, Osmium, Iridium, Gold and Astatine.
Oxidation states of elements 104 onwards are not known.

Generally, metals attain positive oxidation numbers only. Non metals can have either positive or negative oxidation states. If an oxidation number is a negative value, it can be deduced that it's a non metal element.
The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.
Ca & Mg
Colored ions in solution, multiple positive oxidation states.
Yes. For example, chlorine in compounds can have the following oxidation states: -1 (most common), +1, +3, +5, and +7.
Oxidation number is oxidation states of an element. It can be positive or negative.
0, neither positive or negative. They are the noble gases, and as such, very unreactive
Generally, metals attain positive oxidation numbers only. Non metals can have either positive or negative oxidation states. If an oxidation number is a negative value, it can be deduced that it's a non metal element.
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

Metals form cations and have positive oxidation states.
Metals are electropositive elements and have low ionnisation enthaply, so there tendency to lose an electron is very high, so they show only positive oxidation states.
Nitrogen is an element, it can form either negative or positive ions. It has oxidation states of 5, 4, 3, 2, 1, -1, -2, -3 with +3 being the most common.
