The oxidation number of a chemical tells how many electrons it will gain or lose in a reaction. A positive oxidation number means that it will lose electrons, and a negative means it will gain them. A chemical with an oxidation number of 2+ would usually lose 2 electrons in a reaction.
All of the Alkali earth metals (second column of the Periodic Table) have an oxidation number of 2+.

What do the oxidation number of 2 and -2 imply?
An oxidation number of 2 means the ion has two more protons than electrons. An oxidation number of -2 means the ion has two more electrons than protons.
What do the oxidation number of plus 2 and -2 imply?
The oxidation number illustrates the number of electrons that a particular atom has partially/completely donated/accepted. +2 stands for donation of two electrons such as magnesium in magnesium salts. The oxidation number of -2 stands for obtaining two electrons such as an oxygen atom in an oxide.
What is the oxidation number of O in CsO3?
On the face of it without knowing the structure it would be -2 however that would imply an oxidation number for Cs of +6. Fortunately this compound does not exist which explains the weird oxidation number for Cs. There is a compound Cs11O3 and we get a fractional oxidation number of 6/11- Cs11O3 must contain some Cs-Cs bonding.
What is oxidation number oxygen?
The oxidation number of oxygen is -2 in most of its compounds
What is the oxidation number of Ca?
The oxidation number of Calcium (Ca) is +2
What is the common oxidation numbers for calcium?
The only oxidation number is 2+.
What is the oxidation number of Barium?
The oxidation number of barium is +2.
What is the oxidation number of Ti in TiO?
The oxidation number of Ti in TiO is +2. This is because oxygen typically has an oxidation number of -2 and there is only one oxygen atom in TiO, so the oxidation number of Ti must be +2 to balance out the charges.
In CaSO4 the oxidation number of Ca is that of S is and that ofO is?
In CaSO4, the oxidation number of Ca is +2, the oxidation number of S is +6, and the oxidation number of O is -2.
What is the oxidation number of H2CO2?
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
What is the oxidation number of Cr in CaCrO4?
+2 for Ca, +6 for Cr, -2 for each O
What is the oxidation number of CH3OH?
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
