Which is larger Ba or Ba2 plus?

Answer 1

Neither..they both have approximately the same weight as electrons are virtually weightless.bt the ba2 plus wud have to combine with another element for charge stability and the compound it forms shud be heavier than ba.

Answer 2

Ba2+ is larger than Ba because Ba2+ has lost two electrons, resulting in a decrease in electron-electron repulsion and a larger effective nuclear charge, leading to a smaller atomic size.

Answer 3

Ba is larger
