Oxygen is in group 6, and so it has 6 valence electrons. It needs to more to make an octet, so it will GAIN TWO electrons, and become negative 2, i.e. O^2-.
Oxygen ions are: O(2-), O(2+), O(1+), O(1-).
The isotopes of a given element, such as oxygen-16 and oxygen-18 have the same number of protons in their nuclei, but different numbers of neutrons, and therefore different mass numbers. Oxygen-16 has 8 protons (its atomic number) and 8 neutrons, while oxygen-18 has 8 protons and 10 neutrons. As long as they are neutral atoms, they also both have 8 electrons. An ion is an atom of an element, that has lost or gained one or more electrons, developing a positive or negative charge. When an oxygen atom ionizes, it gains two electrons, forming an oxide ion with a charge of 2-. The oxide ion would still have the same number of protons (8 for all oxygen atoms and ions), and it would have the same number of neutrons as the isotope that became the ion, so it would have the same mass number as the particular oxygen isotope that gained the two electrons, but the number of electrons would not equal the number of protons as it would in a neutral atom.
Carbon would share electrons with the oxygen to form carbon monoxide or carbon dioxide.
Each electron has a 1- charge, so an atom that has gained 5 electrons has a charge of 5-.
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.
It depends! if an ion has 7 electrons on its outter region and it decides to gain 1 that would make it stable! if you have 8 on your second region and have an extra electron, you can loose it and the ion will be stable again!
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
Nitrogen would have a neutral charge and eight valence electrons.
Oxygen needs 8 electrons to have no charge.

Under normal conditions of temperature and pressure, oxygen gains electrons. The outermost orbital in an oxygen atom has four electrons., i.e., the outermost orbit has six electrons. Hence, to reach the octet configuration, oxygen can take two more electrons. Thus, oxygen is electronegative.
Carbon would share electrons with the oxygen to form carbon monoxide or carbon dioxide.
Each electron has a 1- charge, so an atom that has gained 5 electrons has a charge of 5-.
An atom of oxygen has 8 electrons, an O2 Molecule would therefore have 15, I think.
