The number of electrons, number of valence electrons and the name of the element with electronic configuration 1s 2 2s 2 2p 6 3s 2 3p 5 has to be given. Concept Introduction: Electrons: Electrons have an electric charge of -1 , which is equal but opposite to the charge of a proton, which have an electric charge of +1 . All atoms have the same number of electrons as protons, so the positive and negative charges cancel out making atoms electrically neutral. Valence electrons: Valence electrons are electrons that exist in the outermost shell surrounding an atomic nucleus.
