Why does Ca have a bigger atomic radius than Na? The periodic trend for atomic radius says that the lower and more to the left an element is, the greater it's atomic radius. In our case, Na is more to the left, but the Ca is lower down. How do we reconcile this?

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...

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...

Could you please give me answers for these ? thanks 1. Atomic radius decreases as we move from left to right in the periodic table. Which of the following is the BEST explanation for this trend? a. The electrons in the valence shell increase in number and thus interact more with one another as we move from left to right. b. There is more shielding of the inner electrons as we move from left to right. c. The electrons in...

Atomic radius Nbonding The radius of an atom describes the distance between the nucleus and the outermost electron. This distance is very small so it is often reported in picometers (101 m) or angstroms (10-10 m). One way of measuring the atomic radius is to observe the distanc between bonding atoms. The distance between the nuclei of the bonding atoms is equal...

Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...
