Corrected: All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions with respectively positive (on loosing) or negative charge (on gaining electrons, as oxygen tends to do).
NO: 2-. It's the same as minus 2, but is written as 2- for conventions.
Zero
The resulting oxygen ion has a charge of -2.
ketone bears negative charge on the oxygen atom of the carbonyl group.
During oxidation an oxygen atom gain two electrons.
Carbon as an atom has no charge, as all atoms are neutral particles. This is because they have equal numbers of protons and electrons, so the carbon atom has no charge.
The oxygen atom is neutral.
Cobalt is an element, there is no oxygen.
Zero
Oxygen -2 Hydrogen +1
Oxygen needs 8 electrons to have no charge.
ALL atoms whatsoever DO NOT have a charge!! They're neutral.
The resulting oxygen ion has a charge of -2.
ketone bears negative charge on the oxygen atom of the carbonyl group.
During oxidation an oxygen atom gain two electrons.
No. On its own oxygen is neutral. Its ion, the oxide ion, has a negative charge
Carbon as an atom has no charge, as all atoms are neutral particles. This is because they have equal numbers of protons and electrons, so the carbon atom has no charge.
a partially negative charge.
