Since elements in the same family have the same number of valence electrons, their dot structures will look the same, too! How many valence electrons does oxygen have? The electrons in per shell of oxygen is 2 and 6. A.35 B.34 C.36 D.79 C. 5 b. Oxygen with the symbol O has the atomic number 8 which means it is the 8th element in the table. How many valence electrons (electrons in the outer energy level) does oxygen have?Oxygen is a non-metal element found in Group 16 of the periodic table. Since an oxygen atom has six valence electrons and wants eight, it uses two of its six valance electrons for bonding. If you're talking about O--, then it has 10 electrons. As a result, the hydrogen ends of the water molecule have a slight positive charge while the oxygen end has a slight negative charge. The strange case of Copper valence electrons. Select one: a. Oxygen has 6 valence electrons, two in the 2s subshell and four in the 2p subshell. Oxygen element lies in 16th group and 2nd period of periodic table. If a neutral oxygen atom gains two electrons, what will its overall charge be? The atomic number of oxygen is 8 and its atomic mass is 16. Copper has 29 electrons in total, so the rearmost electrons are lined up as …4s^2-3d^9. How many valence electrons (electrons in the outer energy level) does oxygen have?Oxygen is a non-metal element found in Group 16 of the periodic table. What is the number of valence electrons in oxygen? Oxygen belongs to 'p' period of periodic table. Middle School Life Science: Tutoring Solution Hydrogen has only 1 electron, which is used to … Oxygen is found in the sixth group, therefore it has six valence electrons.There are 6 electrons in the valence (outermost) shell of oxygen.8 electrons, minus 2 for the first orbital, second orbital will have 6 makeing thme valenceAll of the elements have the group have the same amout of valence electrons. An oxygen atom can form two covalent bonds. How many electrons, protons, valence electrons, and neutrons are in Oxygen? Oxygen atom has 8 electrons with 2 in its inner shell(K-shell) and 6 in its outer or valence shell(L-shell). Solved: How many valence electrons does an oxygen atom have? Answer (1 of 4): Oxygen is a non-metal element and its symbol is O. A.-2 B.+1 C.+2 D.-1 A. An atom's number of valence electrons dictates how many bonds the atom can form. How many electrons are in an ion of Br -1 ? The electronic configuration of oxygen is 1s2 2s2 2p4. For Copper, the configuration is a little unsettling — a more stable configuration would be to have 10 electrons in the 3d shell, and this is exactly what we observe! 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.
