It can be a any group. Generally they shows +2 in group 2.
2 answers
The oxidation number for group 2 elements is typically +2. These elements have 2 valence electrons that they can lose to form a 2+ cation.
2 answers
Group 2 elements have 2 valence electrons. This is because they are located in group 2 of the periodic table, which corresponds to the number of valence electrons in the group. Examples of group 2 elements include beryllium, magnesium, calcium, strontium, barium, and radium.

No, DNA does not have a 2' OH group in its structure.
1 answer
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).

Sodiumis in group 1 and its cation is charge +1. Calcium is in group 2 and the cahrge on its cation is +2. etc.
1 answer
The ionic charge of a group 1A, 2A, or 3A ion is determined by the number of electrons lost or gained to achieve a full valence shell. Group 1A ions lose 1 electron to attain a +1 charge, group 2A ions lose 2 electrons for a +2 charge, and group 3A ions lose 3 electrons for a +3 charge.

Oxygen belongs to group 16 (also known as Group VIA) and period 2 on the periodic table.
4 answers
The combining ratio between elements in group 2 (alkaline earth metals) and elements in group 15 (nitrogen family) is typically 3:2. For example, magnesium oxide (MgO) forms when one atom of magnesium (group 2) combines with one atom of oxygen (group 16), resulting in a 1:1 ratio.

The ionic character increases for group 2 compounds as we go down the group. The metallic character also increases.
1 answer
Group 1 or alkali metals (+1 oxidation number).
Group 2 or alkaline earth metals (+2 oxidation number).
4 answers
Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.
