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 are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
What is the oxidation number of the alkiline earth metals?
+2 for alkaline earth metals
What is the oxidation number in Alkaline Earth Metals?
They have +2 O.S.
Does a metal or nonmetal have both positive and negative oxidation numbers?
All metals have positive oxidation numbers. Non-metals may have positive or negative oxidation numbers and some metalloids have both positive and negative oxidation numbers as well
Can metals have positive and negative oxidation numbers?
No, they can't only have positive oxidation numbers in compounds.
What are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
What is the oxidation number of the alkiline earth metals?
+2 for alkaline earth metals
What is the oxidation number in Alkaline Earth Metals?
They have +2 O.S.
Do metals have both positive and negative oxidation numbers?
No, the can only have positive oxidation numbers
Does a metal or nonmetal have both positive and negative oxidation numbers?
All metals have positive oxidation numbers. Non-metals may have positive or negative oxidation numbers and some metalloids have both positive and negative oxidation numbers as well
Which group has a plus 2 oxidation number?
Group 2 or alkaline earth metals
Can metals have positive and negative oxidation numbers?
No, they can't only have positive oxidation numbers in compounds.
What oxidation states can the alkaline earth metals exhibit?
0 and 2 oxidation states, and in some cases, 1 also
Why is it that the hydrogen placed at the alkali earth metal group?
It is in alkaline group.Not in alkaline earth group.It is in alkaline group because, Hydrogen has maximum oxidation number of +1.It react with Halogens.Displaced by other alkaline metals.
How do oxidation numbers determine if an element is a metal or a nonmetal?
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.
What elements tend to have multiple oxidation numbers?
Transition metals
Where on the periodic table has a positive oxidation number?
Positive oxidation numbers are most common with the metals - groups 1 to 13. However there are many well known compounds where non-metals have positive oxidation numbers- for example NaClO4 where Cl has an oxidation number of +7
