Does P or Sb have a larger atomic radius?
Does P or Sb have a larger atomic radius?
Thus as group 14 elements are arranged in group as N, P , As and Sb, Sb has largest atomic radius.
Which has a larger atomic radius n or SB?
The element sb has the larger atomic radius.
What is the atomic radius of P?
195Â pmPhosphorus / Van der Waals radius
Why is the atomic radius of oxygen larger than nitrogen?
When moving along a period, the atomic radius is supposed to decrease. However oxygen has slightly higher atomic radius than nitrogen. This is because nitrogen has an electronic configuration 2p3 having its orbittal half filled and hence there is less repulsion between the electrons.
Which one of these elements has the largest atomic radius?
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
Why the radius of an atom is smaller than its anion?
The electrons are strongly attracted by the Nucleus and pulled inwards. As a result, the size decreases. On the other hand, the anion is larger because it is formed by gain of electrons.
Why the ionic radii of negative ions are larger than the size of their parent atoms?
Consider first the relative sizes of an ion and its parent atom. The opposite is true of negative ions. When electrons are added to form an anion, the increased electron-electron repulsions cause the electrons to spread out more in space. Thus, anions are larger than their parent atoms.
Why are cations smaller than their corresponding atoms?
Cations and Anions These cations are smaller than their respective atoms; this is because when an electron is lost, electron-electron repulsion (and therefore, shielding) decreases and the protons are better able to pull the remaining electrons towards the nucleus (in other words, Zeffincreases).
What is the atomic radius of SB?
206Â pmAntimony / Van der Waals radius
Which has a larger atomic radius?
francium

Why the size of oxygen is exceptionally small?
Due to strong electronegativity (3.5) in oxygen atoms, the attraction between the outermost electrons and nucleus increases exceptionally and so the electrons are more tightly held by nucleus which reduces the size of the oxygen atom to exceptionally small.
