An oxygen molecule is O2. Each oxygen atom has 8 electrons, so there are 16 electrons in an oxygen molecule.
Why does oxygen have 2 valence electrons?
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8.
This results in the oxygen ion having an octet (8) of valence electrons. solution. expand. Was this answer helpful? Answer and Explanation: 1 The number of protons is the same as the number of electrons in an element. Therefore, since oxygen has eight protons it has the. Oxygen requires two electrons to become an ion. Oxygen belongs to group six in the periodic table so it has six electrons in its valence shell.
Valence electron of oxygen is 6 and each oxygen atom will share 2 valence electrons to make a bond. From the electronic configuration of the oxygen atom, we come to know that the number of electrons present in the outermost shell i.e., 2rd shell is 6 electrons. How many electrons does an Oxygen atom need to fulfill the octet rule by filling its valence shell?a) 8.b) 4.c) 1.d) 2.e) 6. The oxygen has 8 electrons. Complete step by step answer: This question is very simple. It just requires the basic knowledge of the periodic table. From the.
