Oxygen is a non metal element. There are 8 electrons in a single atom.
The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8. For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
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.
The element with 8 protons and 8 electrons is oxygen (O). The presence of 11 neutrons indicates a specific isotope of oxygen, oxygen-19.
The element with six electrons in its outer shell is oxygen.
