Which one has the smallest radius?

helium

Which of the following cation has the smallest radius?

The ionic radius of Ni2+ is minimum.

Which is the smallest size?

Ionic size varies inversely with nuclear charge. Higher the nuclear charge, smaller the radii. Thus P5+ because of the high nuclear charge, has the smallest size.

Which is smaller Mg2+ or Na+?

mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus. …

Is Na+ smaller than K+?

K+ is larger than Na+ because the ionic radius increases in a particular group on moving from top to bottom due to increase in the principle energy shell though the number or electrons in the valence shell remain the same.

Is Au 3+ smaller than Au+?

Answer. Answer: Au+ or Au3+: Au3+ is smaller than Au+ for the same reason as part (b).

Answer. Answer: P3 ” is larger radius than N3-.

The Al3+ ion has an electron arrangement of 2,8 ie two filled electron energy levels. The third electron energy level is further away from the nucleus than the second and so the P3- ion is the larger ion.

Which has a larger radius n3 or N?

a) The atom has three more electrons than an atom of just N. These extra electrons cause the atomic radius to increase. Therefore, the smaller member of the pair is .

Why is nitrogen larger than oxygen?

Nitrogen’s atomic radii is larger than both Oxygen and Fluorine because when you move from left to right in a period the number of protons increase but since the shell number remains the same the effective nuclear charge on the outer most/ valence electrons increases which try to exert more force to pull the electrons …

Does oxygen have a larger atomic radius 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.

Is nitrogen larger than oxygen?

Nitrogen molecules (N2) are larger than oxygen molecules (O2) so therefore, pure nitrogen will permeate the walls of your tires less than oxygen molecules. But by how much? Well, a nitrogen molecule measures roughly 300 picometers while an oxygen molecule measures 292 picometers.
