The atomic radius of Na is greater than that of Si because as you move to the right across the Periodic Table there are more electrons which cause more attraction between the protons and electrons which cause them to pull closer together.
What else can I help you with?
Of the following which has smallest atomic radius sulfur aluminum sodium barium?
Atomic radii become larger as you go from top to bottom of the periodic chart, but they get smaller as you go from left to right. Therefore, the elements with the smallest radii are in the upper right hand corner. Of S, Al, Na, and Ba, sulfur is the closest to the upper right corner and has the smallest radius of those elements.
What is the difference between the atomic radii of sodium (Na) and potassium (K)?
The atomic radius of sodium (Na) is smaller than the atomic radius of potassium (K). Sodium has a smaller atomic radius because it has fewer electron shells compared to potassium.
What element is the largest Mg S Na CI?
Sodium (Na) is the largest element among Mg (magnesium), S (sulfur), Na (sodium), and Cl (chlorine) when comparing their atomic radii. Sodium has the largest atomic radius because it is located in the third period of the periodic table, whereas magnesium is smaller due to being in the second period.
Why do radii of atoms become smaller from sodium to chlorine?
The atomic radii decrease from sodium to chlorine due to the increase in effective nuclear charge as you move across the period. This results in a stronger pull on the valence electrons, causing the atomic size to decrease. Additionally, the increased number of protons in the nucleus as you move from sodium to chlorine also contributes to this decrease in atomic size.
What is the difference between atomic radii and ionic radii?
Atomic radii refer to the size of an atom, measured as the distance from the center of the nucleus to the outer electron shell. Ionic radii, on the other hand, refer to the size of an ion, which can be larger (anions) or smaller (cations) than the corresponding atom due to the gain or loss of electrons.

Why are the ionic radii of metallic elements smaller than the atomic radii of the same elements?
The ionic radii of metallic elements is smaller than its atomic radii, because the ion has less electrons. This gives it a smaller electron cloud and makes the atom smaller.
What element is the largest Mg S Na CI?
Sodium (Na) is the largest element among Mg (magnesium), S (sulfur), Na (sodium), and Cl (chlorine) when comparing their atomic radii. Sodium has the largest atomic radius because it is located in the third period of the periodic table, whereas magnesium is smaller due to being in the second period.

Additionally, the increased number of protons in the nucleus as you move from sodium to chlorine also contributes to this decrease in atomic size.
Which element has a larger radius magnesium or sulfur?
Sulfur has a larger atomic radius than magnesium. This is because as you move down a group in the periodic table, atomic radius increases due to the addition of more electron shells. Magnesium is higher up in the periodic table than sulfur, so it has a smaller atomic radius.
What is smaller in radius uranium or plutonium?
The atomic radii of uranium and plutonium are identical.
What elements would have the largest atomic radii sulfur oxygen selenium tellurium?
This element is tellurium with a covalent atomic radius of 140 pm.
Calcium and Sodium have very nearly the same radii?
No sodium has 11 electrons which means its valence are in the 3s2 orbit while Calcium has 20 electrons its valence electrons are in the 4s2 orbit which is much larger in terms of atomic radii
Are the atomic radii of Mn and Fe same?
No, the atomic radii of Mn (manganese) and Fe (iron) are not the same. Typically, atomic radii decrease across a period (from left to right on the periodic table), so Fe would have a smaller atomic radius compared to Mn.
Do the elements to the right of the periodic table have small or large radii?
Elements to the right of the periodic table have smaller radii due to increased effective nuclear charge, which attracts the electrons closer to the nucleus. This results in a greater pull on the outer electrons and smaller atomic radii overall.
Is smaller in radius uranium or plutonium?
The atomic radii (empirical) of plutonium and uranium are identical - 175 pm.
