What is the total charge on an oxygen ion that has 8 protons 8 neutrons and 10 electrons?

Consider an atom of oxygen in which the nucleus contains 8 protons and 8 neutrons. If it is doubly ionized, what is the charge of the oxygen ion and how many electrons remain in the 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 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.


How many electrons in NO?

There are 16 electrons in this ion. 7 from nitrogen, 8 from oxygen and the other one is from the ionic charge.


If an oxygen atom gains two electrons to become an oxygen ion what is the electric charge?

-2


How many electrons must the oxygen atom lose to be stable?

Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.


What charge would an oxygen atom with 10 electrons have?

An Oxygen atom would never contain 10 electrons on its own. It would have a maximum of 8 electrons at one time, unless the "oxygen atom" you are referring to is in fact an oxygen ION, in which case the charge would be -2. However, an oxygen ion can never be "by itself". It must be bonded with either itself as a diatomic or with another element as a compound.


How many valance electrons are in the oxygen family?

The # of Valance electrons in the oxygen famly is 6


How many core electrons are in oxygen ion?

Oxygen has 6 core electrons.


Describe in terms of electrons what happens when an oxygen atom forms an oxygen ion state the charge on the oxygen ion formed?

Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-


When an oxygen atom becomes an oxide ion it has a charge of -2 why?

It has gained 2 electrons.
