answer a b or c
Why is the atomic radius of magnesium ion much smaller than that of a neutral charged magnesium atom? (See the atomic radius graph) The magnesium ion's electrons require less space. No electrons are lost, they move to unoccupied spaces about the nucleus. The magnesium ion has fewer principle quantum energy levels, this causes a decrease in atomic radius. The magnesium ion has a higher Z-effective nuclear charge. The magnesium ion has more principle quantum energy...

Consider the following information for sodium and chlorine: Atomic radius: Na (186 pm) and Cl (100pm) Ionic radius: Na+(102pm) and Cl-(181pm) Why does the atomic radius decrease while ionic radius increase? The outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. Monatomic ions are bigger than the atoms from which they are formed. The outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. The...
