Which atom is larger Li or Na?

Updated on April 05, 2026
The size of an atom decreases from left to right. As the attractive forces become stronger, the electrons are drawn closer to the nucleus, and thus the atom is smaller. Li and Na are in the same group. As the atomic mass increases as you move down the periodic table, Na has a larger atomic radius.
Which has a larger atomic size 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.
Is Li bigger than Li?
A cation has less electron than the neutral form of the element. Remember that the atomic radius is dependent upon the number of electrons (i.e. high number of electrons means larger radius). Li+ has 1 electron less than Li. Therefore, Li+ is smaller than Li.
Why is Li smaller than Na?
Li has 2 shells and Na has 3 shells. So Li is smaller than Na. This is due the fact that lithium has two orbitals while sodium has four orbitals . Hence size of Na atom is bigger than that of Li .
Which atom is bigger among Na and Mg Why?
It is due to increased nuclear charge because of which force of attraction between the nucleus and valence electrons increases therefore atomic size decreases, so Na is bigger in size than Mg.
Which is bigger Cl or Cl?
The size of Cl⁻ is bigger than Cl. The electronic configuration of chloride is Cl: [Ne] 3s² 3p⁵ The number of electrons in chloride is 17 electrons. The number of electrons in chloride is 18 electrons. The nucleus cannot hold 18 electrons as tightly as 17 electrons.
Which is bigger in size Na+ or Cl?
Na atoms are larger than Cl atoms because the electron cloud of Cl is pulled in more tightly by the increased number of protons in the nucleus. 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 is smaller CL or CL?
Answer: Uncharged Cl is smaller than Cl-ion. In general, when an element becomes charged the anion will get the bigger and the cation will get smalled compared to the uncharged element.
Which has a larger atomic radius Na or Na 1?
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.
Which atom is bigger Na or Mg Why?
Why Na atom is bigger than both Li and Mg atoms?
REASON- As the atomic number increases the number of proton also increases. REASON – The number of electron shells in the atom gradually increases due to which the size of atom increases. In case of Sodium and lithium, sodium occurs in the lower shell so its size is bigger.
Why is Na2 larger than Cl2?
Na atoms are larger than Cl atoms because the electron cloud of Cl is pulled in more tightly by the increased number of protons in the nucleus. 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 has the largest atomic size: Br, Br- or Br+?
Why are Nana atoms larger than Cl atoms?
Na atoms are larger than Cl atoms because the electron cloud of Cl is pulled in more tightly by the increased number of protons in the nucleus.
Why is the anion Cl- greater than Na?
Na and CL are from third period, Basically CL atom is smaller than Na atom. but due to formation of Na+ cation, Na atom has lost a shell (M-shell and 3s1 orbit) and due to formation of CL- anion Cl Atom has gained one electron. thats why the Cl- anion is greater in size. , B.E. Cl- is greatest among them.
Why is the size of Cl- larger than F- and Li+?
And among these two, Cl- is greater in size than F- , as the ionic radii increases down the group. Cl- is larger in the size. because it has 18 electron and just 17 proton. so the force acting on the electron is less as compared to chlorine with 17 electron. similarly size of Li+ is smallest among these four element.
