How many electrons are there in an oxygen atom?

Answer 2: Oxygen is the 8th element in the periodic table. This means that oxygen has 8 protons and 8 electrons. In order to get the number of neutrons you take the atomic weight in this case 15.9999~16 and you subtract it by the number of protons (16-8).

One may also ask, does oxygen have 8 electrons? Oxygen is #8 in the periodical table. First electron shell can hold 2 electrons; second, 8. Therefore, out of 8 electrons, 2 go to the first shell and 6 to the second; valence electrons are the ones on the outermost shell (there are some exceptions, but they are much further down the table).

Similarly, how many electrons are negative o2?

An oxygen atom with a charge of negative two, written as superscript 2-, would have 10 electrons. Neutral atoms of oxygen have 8 electrons.
