The oxygen atom is neutral.
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.
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.
It's 4 times heavier.
No. On its own oxygen is neutral. Its ion, the oxide ion, has a negative charge
No. The oxygen atom in a water molecule has a partial negative charge, and so it would not readily interact with Cl-, another negatively charged species.
Oxygen -2 Hydrogen +1
Oxygen goes to -2 Hydrogen to +1
Oxygen needs 8 electrons to have no charge.
oxygen atoms have -2 charge where hydrogen generally have +1

It would have a negative charge. It would be a negative ion with a 2+ charge.Remember: when an atom gains electrons they become NEGATIVE.when an atom loses electrons they become POSITIVE.
A proton is a single positive charge in the nucleus of an atom. The number of protons determine what the atom is. Hydrogen has one proton, compared to eight for oxygen.
Cobalt is an element, there is no oxygen.
Zero

Oxygen
ALL atoms whatsoever DO NOT have a charge!! They're neutral.
