What is the core electrons?
Asked by Chetan Bhardwaj | 26 Dec, 2013, 09:13: PM
Expert Answer
Core electrons are the electrons in an atom which are not valence electrons and thus do not participate in chemical bonding.
For example: Oxygen has a total of 8 electrons, 6 of them being valence electrons. So the remaining 2 electrons are core electrons.
