# Is CL Smaller Than F?

## Is Br or Br bigger?

Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.

Explanation – when Br gain an electron then one electron in Br increases and this lead to increase in atomic size..

## Which is smaller Na or Na+?

Na+ is smaller than Na because, it has given away one electron because of which the electron shielding gets stronger due to more protons and less electrons. … of electrons increase thus extending the attraction to one more, leading to decreases nuclear attraction .

## Is CL smaller than S?

Which ion has the larger atomic radius: S= or Cl-? In general, both have the same electrons (repulsing each other the same amount), but the Cl Chlorine has more protons which would attract more. So, the general answer is the Cl will become a tighter configuration in 3D.

## Why is fe3+ smaller than fe2+?

(For comparison, the Fe atom has a radius of 140 pm). This is because the outermost electron in the Fe2+ ion is pulled off to form Fe3+ ion. As the electrons are removed, it reduces the repulsion increasing nuclear charge experienced by each of the other d electrons and decreases the size of the ion.

## Why is F larger than Na+?

F atomic number is 9 having 9-electrons & 9-protons. After gaining electron, it becomes F-having 10-electrons and 9-protons. Now due to excess of electron, electron-electron repulsion becomes greater as compared to electron-proton attraction. … After gaining electron, it becomes Na+, having 10-electrons & 11-protons.

## Which is larger F 1 or F and why?

F-1 is bigger because it has one more electron than F, therefor making it bigger.

## 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.

## What is the Zeff of CL?

for Cl-: Zeff=17-9=8. This is for your rules, where the core electrons contribute 1 to S and the valence electrons contribute nothing.

## 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.

## Which one between CL and CL minus would have more size Why?

Because the nucleus can’t hold the 18 electrons in the Cl- ion as tightly as the 17 electrons in the neutral atom, the negative ion is significantly larger than the atom from which it forms.

## Which is smaller Cl or Br?

As Br is smaller than Cl; therefore, Br- have a smaller ionization energy than Cl-. In short, since the outermost electron in bromine is farther from the nucleus than the outermost electron in chloride, it takes less energy to remove the outermost electron in bromide.

## Which is larger Cl or Ar?

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.

## Which is larger 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.
