The zero stands for "zero charge". In other words, a neutral atom must have exactly one electron for every proton. Be careful not to post spoilers! All atoms have the same number of electrons as protons, so the positive and negative charges "cancel out", making atoms electrically neutral. 208 Rhodium has 45 protons, 58 neutrons and 45 electrons: 46: Palladium: Palladium has 46 protons, 60 neutrons and 46 electrons: 47: Silver: Silver has 47 protons . .ec_product_star_on{ border-bottom-color:#222222 !important; color:#222222; border-bottom-color:#222222; } In other words, it has no charge whatsoever and is therefore neither attracted to nor repelled from other objects.
