Why Is Cu2 More Common Than Cu ? Cu2+ is more stable than Cu+. Stability depends on the hydration energy (enthalpy) of the ions when they bond to the water molecules. The Cu2+ ion has a greater charge density than Cu+ ion and thus forms much stronger bonds releasing more energy. How is Cu2+ different

Which One Of The Following Has The Largest Atomic Radius? Na has the largest atomic radius. Reason: Li : belongs to the 2nd period. Na and Cl : belong to the 3rd period. Which element has the largest atomic radius sodium or aluminum? Sodium has fewer electrons than aluminum and therefore a weaker inward pull
Which Is More Difficult To Remove An Electron From Mg Or Na? It doesn’t take much energy to remove one electron from a sodium atom to form an Na+ ion with a filled-shell electron configuration. The second ionization energy of Mg is larger than the first because it always takes more energy to remove an
Does Removing An Electron Use Or Release Energy? When electrons are removed from an atom, that process requires energy to pull the electron away from the nucleus. Addition of an electron releases energy from the process. The energy change that occurs when a neutral atom gains an electron is called its electron affinity . Does
