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...

Classify each statement about effective nuclear charge, Zeff, as true or false. True False Effective nuclear charge is dependent on the number of electrons present in an atom. In a N atom, a ls electron has a greater Zer than a 2s electron. Electrons in a p orbital are more effective than those in other orbitals at shielding other electrons from the nuclear charge. Als electron in a B atom has a smaller Zeff than a ls electron in a...
