Jon. atoms need to have a full valence shells to become stable. Valence electrons are those found on the atom's outer shell. Therefore, from 8 electrons, 2 go to the first Shell and 6 to the second; Valence electrons are the ones that are in the outermost layer (there are some exceptions, but they are much lower in the table). As element # 8, it has eight total electrons when it is not an ion. As its The octet rule. Oxygen is in 6th column and they have 6 valance electrons. given below: 6 CO2 (Carbon dioxide) An oxygen atom, if it is a neutral atom, will have six valence electrons. five . Oxygen has 6 valence electrons. Valence electrons are the electrons in the outer energy level of an atom that can participate in interactions with other atoms. Hydrogen has relatively low electronegativity, so that when hydrogen bonds to oxygen to form water molecules (H 2 O) the shared electrons spend most of their time orbiting the oxygen atom. Remember that there are 5 3-d orbitals, so having 6 electrons in these 5 orbitals is unstable, so Cu+2 will lose the extra electron in the 3-d. Other elements that share this characteristic include selenium and tellurium. Oxygen has six electrons in its outer shell, so it has 6 valence electrons. Arsenic is a Main-group element, so a quick simplification can be used. Oxygen does not usually occur as a single atom. Two oxygen atoms are bound covalently to get rid of valency and form O2 gas. 9 Answers. To determine valence electrons, add the outermost s and p orbitals. 29 terms. When it does (Monoatomic Oxygen) it has 3 pairs and 2 unpaired. as the total number of electrons an atom can lose, gain, or share at the time 34, 36, and 38 valence electrons were studied.
