प्रश्न
Which is greater in size Fe2+ or Fe3+?
Advertisements
उत्तर १
An anion is greater than an atom since it is formed by the gain of electrons, and so the number of electrons is greater than the number of protons. The effective positive charge in the nucleus is less, so less inward pull is experienced. Hence, the size expands.
उत्तर २
Fe2+ has one extra electron than Fe3+, resulting in its greater size. Fe3+ has a stronger nuclear pull than Fe2+, leading the outermost shell to move closer to the nucleus, causing its size to decrease.
