EB) muttipte-cuoice question How do the core electrons shield the valence electrons? Since they are both negatively charged, the core electrons repel the outer electrons and block the strang attraction by the nucleus. We can't really know where the valence electrons are anyway, 50 we can't say for sure they're being shielded. The outer electrons are too far away to feel the pull of the positively charged nucleus. Because they provide physical protection. Rewatch
