Smallest cation in periodic table
WebbAs a result, magnesium has a smaller radius. Mg 2+ has an ionic radius of 72 pm, while Na + has an ionic radius of 102 pm. And since magnesium has a lower volume and a higher charge, its charge density is higher than that of sodium. The trend of … WebbCations are positively charged ions formed when neutral atoms lose electrons; anions are negatively charged ions formed when neutral atoms gain electrons. It is possible to predict the charges of common …
