What is the oxidation number for group 2 elements?
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
Why do the oxidation numbers in the first two groups tend to be positive?
The oxidation numbers in the first two groups tend to be positive because these elements have a tendency to lose electrons and form cations. Elements in Group 1 and Group 2 have 1 and 2 valence electrons, respectively, making it easier for them to lose these electrons and achieve a more stable electron configuration by forming ions with a positive charge.
Why do elements in group 2 have an oxidation number of -1?
In group 2 elements like alkaline earth metals, the common oxidation number is +2, not -1. This is because these elements tend to lose 2 electrons to achieve a stable octet configuration and form 2+ cations.
Do elements in the s or p block generally have one common oxidation number?
No, this is not the case. Firstly, a simple substance (pure element) always has oxidation number 0. Then there is the fact that when combining with an element more electronegative than the element in question it will tend to have a positive oxidation number while if the element is more electropositive it will tend to have a negative oxidation number.Nitrogen is a good example:-3 in NH3-2 in N2H4-1 in NH2OH0 in N2+1 in N2O+2 in NO+3 in NaNO2+4 in NO2+5 in HNO3Other elements are not as versatile as nitrogen, but a typical non-metal will show all odd or even oxidation numbers over a range of 8 units, as well as zero, while a typical metal will show all odd or even oxidation numbers between 0 and its valence.The elements that do show only one common oxidation number (other than zero) are all of the s-block elements and fluorine and oxygen.
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

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.
How can you use oxidation numbers to predict what an element will bond with?
Oxidation numbers can help predict the way an element will bond by indicating the charge an element is likely to obtain when forming a compound. Elements tend to bond in a way that results in achieving a more stable oxidation state, such as by gaining or losing electrons to achieve a full valence shell. By knowing the possible oxidation states of an element, one can anticipate how it will bond with other elements to achieve a balanced charge in a compound.
Does a metal or nonmetal have both positive and negative oxidation numbers?
A metal typically has only positive oxidation numbers, while a nonmetal can have both positive and negative oxidation numbers. Metals tend to lose electrons (positive oxidation numbers) to form cations, while nonmetals can gain or lose electrons to form a variety of oxidation states.
What is the oxidation number for group 5?
Group5 is belongs to the P block. They shows +3 and +5 numbers.
What is the oxidation number of group 17 elements?
The oxidation number of group 17 elements, also known as the halogens, is typically -1. This is because they have seven valence electrons and tend to gain one electron to achieve a full outer shell configuration.
What block of the periodic table of elements tend to form type II ionic compounds?
Transition metals, which are found in the d-block of the periodic table, tend to form type II ionic compounds. These metals have multiple oxidation states, allowing them to donate different numbers of electrons to form stable ions. This characteristic makes them more likely to form type II ionic compounds compared to other elements.
Why do oxygen and sulfur have the same oxidation numbers?
Oxygen and sulfur have similar electronegativities, so they tend to share electrons in covalent bonds. This leads to similar oxidation states for both elements in compounds. Oxygen typically has an oxidation state of -2, while sulfur usually has oxidation states of -2, +4, and +6.
