Why is chlorine ion larger than chlorine?

Explanation: Chlorine has a proton number of 17. Hence, we can deduce that the forces of attraction exerted on the outermost electron in chloride ion is lesser than chlorine atom, since there are more electrons. Conclusion, chloride ion has a bigger atomic radius due to an increase in number of electrons.

Why is the size of Cl ion is larger than Cl atom where as size of K+ ion is smaller than that of K atom?

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 the ionic radius of a chloride ion larger than the ionic radius of a sodium ion?

Why is the ionic radius of a chloride ion larger than the ionic radius of a sodium ion? (A) A chloride ion has one more occupied electron shell than a sodium ion.

What is the difference between chlorine and chlorine ion?

Chloride ion is the reduced form of chlorine atom. Chloride has 18 electrons compared to seventeen electrons of chlorine, and both have seventeen protons. Therefore, chloride has a negative (-1) charge whereas chlorine is neutral. Chlorine is more chemically reactive than chloride because it is more unstable.

Why does chlorine have a smaller atomic radius than sodium?

As the no. of protons in Cl is more than Na, the nuclear force in the nucleus of Cl is more than that of Na which holds the valence electrons more tightly resulting in small atomic radius of Cl than that of Na.

Why is chlorine atom smaller than magnesium?

Since chlorine’s 17 protons are greater than magnesium’s 12 protons, chlorine will have a greater effective nuclear charge to draw chlorine’s valence electrons closer to the nucleus and, thus, chlorine is expected to have the smaller atomic radius, while magnesium with the lower effective nuclear charge is expected to …

Would you expect a Cl ion to be larger or smaller than an Mg2+ ion explain?

Would you expect a Cl- ion to be larger or smaller than a Mg2+ ion? Cl- would be larger because there are more electrons which would repel causing the atom to be larger.

Why is the Cl ion larger than ca2+ ion even though they have the same electron configuration?

This is because the nucleus still has 17 protons but the number of electrons in the ion now is 18 unlike the 17 in a neutral atom. Also, inter-electronic repulsion increases. Hence, overall size of the ion is more.

Why does chlorine have a smaller atomic radius than sulfur?

Sulfur and chlorine are in the lowest period, so they have the largest atomic radii. Because sulfur is to the left of chlorine on the periodic table, it will have a larger atomic radius.

Why is chloride ion bigger than sodium ion?

When you’re comparing ions, it’s different as opposed to comparing the elements themselves. The periodic table trends refer to the neutral elements, so naturally, Cl would be smaller than Na because the increasing protons pull in the electrons tighter.

In what way is the chlorine ion different from the chlorine atom chlorine ion than the chlorine atom?

The only difference between an atom and its ions is the number of electrons that surround the nucleus. Example: A neutral chlorine atom contains 17 electrons, while a Cl- ion contains 18 electrons.

What is common between chlorine atoms and chlorine ions?

– Therefore, the number of protons is the same in both of the species. Hence, have the same nuclear charge. – Hence, we can conclude Chloride ion and chlorine atom have same nuclear charge. So, the correct answer is “Option C”.
