6. Oxygen has an electronic configuration of [He]2s22p4
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.
6 valence electrons 1s2 2s2 2p4 These 6 valence electrons are in the outer shell.
Calcium has 2 outer ring electrons, while oxygen has 6 outer ring electrons.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
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!
Oxygen has 6 valence electrons. These are in the outer orbit.
There are 6 electrons present outside the nucleus of an oxygen atom. Oxygen has an atomic number of 8, which indicates the number of protons and electrons in a neutral atom. Since the atomic number of oxygen is 8, it has 8 electrons, with 2 in the inner shell and 6 in the outer shell.
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
The atomic number of an element is the number of protons in its nucleus, which determines its chemical properties. Oxygen has an atomic number of 8 because it has 8 protons. The electrons in the outer shells of an atom can vary, but the number of protons remains constant.

If one atom of oxygen has six electrons in its outer level, then there would be two electrons that are not in pairs. Oxygen atoms typically have a configuration of 2 electrons in the 2s orbital, and 4 electrons in the 2p orbital, with two of those 4 electrons being unpaired.
All elements in the oxygen family have 6 electrons in the outer orbit.
