# Which Ion Is Larger Cl Or P3?

## Why is the ionic radius of p3 greater than si4+?

P3– has one more principal energy level than Si4+ so its valence electrons will be further from the nucleus and it will have a larger ionic radius.

(c) The ions have the same electron configuration, 1s22s22p63s23p6: both have two complete shells; the extra protons in Na+ attract the electrons more strongly..

## Does ionic size increase down a group?

Ionic radii increases down a group. In a group, all the ions have the same charge as they have the same valency (that is, the same number of valence electrons on the highest energy level sub-orbital). Therefore, ionic radii increase down a group as more shells are added (per period).

## How do you know which ion has the largest radius?

Explanation: The ionic radii of cations follow the same trends as atomic radii. They increase from top to bottom and from right to left in the Periodic Table. Thus, the ion with the largest radius is closest to the lower left corner of the Periodic Table, and that is the K+ ion.

## Which has a larger atomic radius He or H?

This site quotes the atomic radius of the helium atom as 31×10−12⋅m . This is smaller than the atomic radius of hydrogen, 51×10−12⋅m , given that while helium has an extra electron, the nuclear charge dominates. … This site quotes the ionic radius of H as 208×10−12⋅m .

## Which is smaller in size Cl or Ar?

Chlorine is smaller than Argon.

## Is K+ or ca2+ bigger?

K+ is larger than Ca2+ . is larger than . |rmK+ is larger than Ca2+ because Ca2+ has the greater charge. |rmK+ is larger than Ca2+ because the increase in electron repulsions that accompany addition of an electron causes the electron cloud to expand.

## Is CL bigger than F?

The order in decreasing size would be Cl- > F- > Na+ > Li+. This can be explained by the following logic. Cl- would be the largest because it has the largest number of electrons, i.e. 18. So, the electron- electron repulsion would be maximum in the chloride ion.

## Which is largest in size Cu+ cu2+ or Cu and why?

The size is Cu > Cu+ > Cu2+ – More the positive charge less will be the radius. The reason is when more positive charge is there more nuclear charges are there and it attract the outermost electron more towards itself, thus the radius is less.

## Which is smaller Cl or K+?

The potassium atom (K) is larger than the chlorine atom (Cl), but the potassium ion (K+) is smaller than the chlorine ion (Cl-).

## Why is p3 larger than al3+?

All three ions have the same number of electrons, but P3- has the fewest number of protons, so it has the least positive nucleus out of the three atoms. Therefore, it will be the largest. Use that logic to determine the relative sizes of the remaining two anions.

## Is Cl or K+ bigger?

In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius.

## Why does the ionic radius decrease from p3 to CL?

drops from Na+ to Si4+ and rise quickly to P3- and it drops to Cl-. … of electrons but rising nuclear charge (as a result of increasing proton number from Na to Si), effective nuclear charge increases from Na to Si, resulting in the electrons being more attracted to the nucleus and thus, a decreasing ionic radii.

## Which ion is larger Cu+ or cu2+?

Cu+ is larger than Cu2+. Cu2+ has a smaller cationic radius due to stronger hold of the nucleus on the remaining 27 electrons after the loss of two as compared to Cu+ where only one electron is lost and the hold of nucleus is less.

## Why is the ionic radius of K+ smaller than CL?

In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius.

## Why is K+ larger than ca2+?

K+ is larger than Ca2+ . is larger than . |rmK+ is larger than Ca2+ because Ca2+ has the greater charge. |rmK+ is larger than Ca2+ because the increase in electron repulsions that accompany addition of an electron causes the electron cloud to expand.

## Which ion is smaller Cl or K+?

In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius.

## Which is larger AR or CL?

Direct link to Ryan W’s post “Cl- has the same number of electrons as Ar, but it…” Cl- has the same number of electrons as Ar, but it has less protons, so less of a positive charge pulling those electrons to the nucleus, so will has a larger radius.
