What Is Oxygen's Charge?

The charge on an oxygen ion is -2. An oxygen atoms contain six electrons in its valence electron shell.

What is oxygen's ionic charge?

The ionic charge of oxygen is 2. You can see this because oxygen is in group 6, so it has 6 valence electrons. Since with a full outer shell of 8 electrons it takes 2 more electrons to become neutral, its charge is 2 (since adding electrons results in a negative charge).

What is the charge of fluorine?

A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
