What is radius ratio of NaCl?
The ionic radius of the sodium ion is 1.16 Å and that of the chloride ion is 1.67 Å. The ratio of radii for the cation and anion is thus r+/r- = 1.16/1.67 = 0.695.
What is the ionic radius of Na+?
227 pmSodium / Van der Waals radius
Why is Na+ smaller than Cl?
Re: Why is Na+ smaller than Na; why is Cl- larger than Cl. Answer: Yes, your reasoning is correct. Consider also that Na+ has as many electrons as Ne, but Na+ has one more proton than Ne to attract the electrons closer to the nucleus, thus resulting in a smaller size compared to both Ne and Na.

How do you find the radius of NaCl?
Each chloride ion is surrounded by six sodium ions. So the coordination number for sodium cation is six. Similarly the coordination number for chloride anion is six. According to the radius ratio rule, the coordination number of six corresponds to the radius ratio of 0.414-0.732.
Which is smaller I Na+ or Na II Cl or Cl?
Na+ ions are smaller than Cl- ions because the Na+ ions have electrons in only two energy levels and Cl- ions have electrons in three levels.
Which atomic radius is larger Na or Cl?
Because the effective nuclear charge rises from left to right in a period, Na has a larger size than Cl. The electronegativity of the nucleus increases as a result of this effective nuclear charge, as does the nucleus’s attraction to valence shell electrons. As a result, the atom’s size shrinks.
Why is the atomic radius of Na larger than Cl?
Na atoms are larger than Cl atoms because the latter have six more positive charges in their nuclei, which pull the atom’s electrons inward more strongly.
Which has a larger atomic radius Na or Na 1?
In general, atomic radius is the distance between the centre of the nucleus and the outermost shell of electrons. In Na atom, the outermost shell is the ‘M’ (3rd shell)shell which has one electron. Hence Na+ is smaller than Na atom.
Which has the largest radius Na or Na 1?
1 Expert Answer Na itself has 11 electrons while Na- has gained one more electron (12) but they are present in the same third shell. Hence the radius is the same for Na and Na- while the radius is smaller for Na+.
What is molecular structure of NaCl?
NaClSodium chloride / Formula
The structure of NaCl is formed by repeating the face centered cubic unit cell. It has 1:1 stoichiometry ratio of Na:Cl with a molar mass of 58.4 g/mol. Compounds with the sodium chloride structure include alikali halides and metal oxides and transition-metal compounds.
Why Na has larger radius than Na+?
Na+ is smaller than Na atom because: Sodium is a Group 1 element, so its only ionic state is Na+. Cations of a given element have a smaller radius than the neutral atom so that Na+ will decrease in size compared with the Na atom. Sodium atoms and sodium ions have the same number of protons. Each one has 11 protons.
Why radius of Na+ is smaller than Na?
Yes Na+ is smaller than Na because Na+ is formed when an electron is lost from the Na atom,Thus the effective nuclear charge increases bcz the number of protons exceeds the number of electrons . This results in bringing the valence shell a little closer to the nucleus because of a very strong nuclear pull.
Does Na or Na+ have a larger atomic radius?
Na+ is smaller than Na atom because: Sodium is a Group 1 element, so its only ionic state is Na+. Cations of a given element have a smaller radius than the neutral atom so that Na+ will decrease in size compared with the Na atom. Sodium atoms and sodium ions have the same number of protons.
Which is smaller Na or Na+ and Cl or Cl?
Na+ion is smaller than Na atom while Cl-ion is bigger than Cl atom.
What is bigger Na+ or Cl?
Na+ion is smaller than Na atom while Cl ion is bigger than Cl atom.
Why does Na+ have a smaller radius than Na?
Na+ is smaller than Na atom because: Cations of a given element have a smaller radius than the neutral atom so that Na+ will decrease in size compared with the Na atom. Sodium atoms and sodium ions have the same number of protons. Each one has 11 protons.

What is the atomic radius of sodium?
Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles. The atomic radius of Sodium atom is 166pm (covalent radius). It must be noted, atoms lack a well-defined outer boundary.
