# Which of the following sequence is correct for ionic radii P3 S2?

P3−

## Is P3 larger than S2?

While S2- has a smaller nuclear charge thanK, the increase in radius due to this, is not sufficient to overcome the incresing size due to the addition of a new shell. In fact, P3-, which would be bigger than S2- (by the isoelectronic species argument), is still smaller than K.

Which is the correct order of ionic radii given below a Ca2+ K Cl S2 P3 B P3 S2 Cl Ca2+ K C K Ca2+ Cl S2 P3 D P3 S2 Cl K Ca2+?

The correct option is: c S2- > Cl- > K+ > Ca2+Explanation:S2- > Cl- > K+ > Ca2+ Among isoelectronic species ionic radii increases with increase in negative charge. This happens because effective nuclear charge Zeff decreases.

What is the order of increasing ionic radius?

Also, when an atom loses electrons, it clings ever more tightly to the ones it has left, further reducing the ionic radius. therefore the order of ionic radii will be: Al3+ (increasing order)

### Which is bigger P3 or Cl?

The ionic radius of P3- is larger than that of Cl-. IE1 of P would be larger than IE1 of Cl. The atomic radius of P is smaller than that of Cl.

### What is the ionic radius of P3?

Trends in ionic radius across a period

Na+ P3-

electronic structure of ion 2,8 2,8,8

How do you arrange ions according to ionic radius?

Explanation:

1. Number of protons per nucleus P
2. Strength of Electrostatic attraction on the electron cloud P

Why does the ionic radius increase down a group?

Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. Ionic radius is the distance from the nucleus to the outer edge of the electron cloud of an ion.

#### What is the ionic radius of Na+?

227 pmSodium / Van der Waals radius

Why does ionic radius increase down a group?

Which ionic compounds are arranged in order to increase ionic radius?

This is question 5B on the practice midterm for fall 2014. The question says, “Arrange S2+, Cl-, and P3- in order of increasing ionic radius. The answer is Cl-, S2-, and P3-.

## What is the Order of charge on ionic radius?

The answer is Cl-, S2-, and P3-. Why is this the order? How do charges affect ionic radius? I think you’ve got a typo in here, but I will assume that you meant to have all negative charges on your ions. The Cl- means that your Cl has gained one electron, S2- means the S has gained 2 electrons, and P3- means the P has gained 3 electrons.

## What is the meaning of P3 and S2-?

I think you’ve got a typo in here, but I will assume that you meant to have all negative charges on your ions. The Cl- means that your Cl has gained one electron, S2- means the S has gained 2 electrons, and P3- means the P has gained 3 electrons.

What order should S2+ Cl-and P3-be arranged?

This is question 5B on the practice midterm for fall 2014. The question says, “Arrange S2+, Cl-, and P3- in order of increasing ionic radius. The answer is Cl-, S2-, and P3-. Why is this the order?
