Why are negative ions usually larger than positive ions

Chemistry

olga nikolaevna [1]4 years ago

<span>In a negative ion, or anion, electron(s) have been added to the atom. This means </span><span>the like charges within the electron cloud are now repelling each other more </span><span>than they were before. The proton count, however, has not changed. So, the </span><span>electron cloud, in response to the added electron(s) expands with that extra </span><span>repulsion. the negative Ions will have gained an electron fill an electron </span><span>shell while a positive Ion will have lost an electron in order to shed its </span><span>outermost shell, thereby making the atom smaller.

Hope this helps!

d perovskite single crystals with suppressed ion migration for high-performance planar-type photodetectors, small
Naily [24]

Due to their improved charge transfer and great environmental stability, 2D Dion-Jacobson (DJ) perovskites have recently received a lot of attention.

Unfortunately, due to the scarcity of high-quality single crystals for precise measurements, their fundamental optoelectronic capabilities are mainly unknown. Here, a reactive, low-temperature-gradient crystallization method is created using 1,4-butanediammonium as a short-chain insulating spacer to generate high-quality 2D perovskite single crystal (BDAPbI4). It is discovered that the BDAPbI4 single crystal exhibits a direct bandgap with effective charge collection (μτ = 1.45 × 10−3 cm2 V−1). The BDAPbI4 single crystal in particular exhibits the expected high ion migration activation energy (0.88 eV).
