Oxygen has 6 valence electrons. These are in the outer orbit.
A neutral atom of oxygen has 6 electrons in it's most outer orbit. Generally, if you count horizontally from left-to-right on the periodic table, you get the number of electrons in its' most outer orbit. You start every row with 1, of course. :) Hope that helps!
Most oxygen molecules contain two atoms, which we breath O2. If we breath pure oxygen (one atom) our lungs would burn. Three molecules of oxygen is the ozone which is unstable and converts back to O2.
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.
Hydrogen ions in water have zero. If you just mean neutral atoms in gas phase, then hydrogen, helium and lithium.
Oxygen have 6 electrons on the outer sell so it need 2 more electrons to gain full outer shell. Magnesium have 2 electrons on the outer sell so It have to lose 2 electrons to gain full outer sell. They combine easily by a strong ionic bond. Its formula is MgO, it has no overall charge.

2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.

All elements in the oxygen family have 6 electrons in the outer orbit.
There are 2 electrons in the valence orbital of a Magnesium atom.

Oxygen has 6 valence electrons (Electrons in the outer most orbit). However, on the whole, Oxygen has 8 electrons as its atomic number is 8.
A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.
Protons, neutrons, and electrons are the three types of particles found in every atom. Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus in specific energy levels.
The nucleus of an atom is positively charged. The electrons that orbit the nucleus are negatively charged to exactly the same degree, which makes the atom neutral.
