A lone, neutral oxygen atom has 6 electrons in its outer shell, but this is not very stable, so oxygen will tend to gain 2 more electrons in order to get a full, stable shell of 8 electrons.

What elements form an ion with a charge of 2?
All the elements in Group 2A (Mg, Ca, etc.). A charge of 2+ is acquired by these metals in order for a more stable state to be achieved.
Can oxygen form a -2 ion?
Yes. Oxygen usually forms the O2- ion.
What is the main difference between an atom and an ion?
Basically, an ion is when the charge of an element is not what it would normally be. So if you took oxygen, which is naturally a -2 charge, and it lost an electron, it would become an oxygen ion with a charge of -1.
What is the charge on the ion that selenium form ionic compound?
selenium has a -2 charge. when it forms a compound with another atom the charge of the compound should be zero unless it has a cahrge in its equation. when compounds form they try to be in the most stable state which is when all their valance elctrons are full which means the charge is zero.
what is the formula with the correct charge for the Hydroxide ion?
A hydroxide ion is composed of one oxygen and one hydrogen atom. In this ion, the oxygen acts as the anion (with -2 charge) while the hydrogen acts as the cation (with +1 charge). Has a charge of −1 Sodium hydroxide, which is usually found in drain cleaners, contain hydroxide ion.
How many electrons does an atom of oxygen need to gain to form an ion with a 2 charge?
It needs 2 electrons for this. Oxygen makes -2 ion by gaining 2 electrons. It is the most stable ion that oxygen makes.
When copper conbines with oxygen to form copper oxide the charge of the copper ion is?
+2
What is the most common charge of oxygen?
The oxygen ion has a coomon charge of '2-'.
When an oxygen atom gains two electrons to become an oxygen ion what is the electric charge?
The resulting oxygen ion has a charge of -2.
What type of Charge does an Oxygen ion has?
It has a negative charge of -2.
What is the charge on the ion typically formed by oxygen?
With a complete outer shell oxygen has a charge of 2-
Which element forms an ion with the same charge as the sulfate ion?
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
What period 2 element is most likely to form an ion with the charge of minus 2?
No clue, mate.
What elements form an ion with a charge of 2?
All the elements in Group 2A (Mg, Ca, etc.). A charge of 2+ is acquired by these metals in order for a more stable state to be achieved.
What electric charge is characteristic for an ion of Cl?
-2 (MINUS TWO) is the usual charge on an oxygen ion.
How can you predict that oxygen will form an O2- ion and not an O3- ion?
All of the elements in column six of the periodic table have a 2- charge
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
