What are oppositely charged ions held together by?

What are oppositely charged ions held together by?

An ionic lattice is held together by strong electrostatic forces of attraction between the oppositely charged ions. The forces act in all directions in the lattice. This is called ionic bonding .

Why the size of CL minus is greater than CL?

(1) It is because cl- ions gain one electron to achieve stable configuration and hence is bigger than cl atom. (4) Inert gas do not form ion as there outermost shell is complete.

Why is Cl more stable?

Chlorine has an exothermic electron affinity, so the chloride ion may be considered more stable than the atom, despite the atom’s neutrality. 17. Cl– has an outer octet of electrons (but not a full shell), and Cl11– has a full outer shell (but more than an octet). 18.

Which is more stable F minus or CL minus?

Fluorine is having outermost Second orbital but Chlorine has outermost third orbital. The energy of third orbital > energy of second orbital. Energy is inversely proportional to Stability. hence , Fluorine is more stable than Chlorine.

Which is more basic F or Cl?

Bases are the exact opposite of acids, ranked in their ability to donate an electron pair. So if fluorine were the most electronegative in terms of acidity, it would be the opposite in terms of base classification. The F would be the strongest base, followed by the Cl, the Br, and lastly, the I.

Is Na+ a stable ion?

Na+ can remain stable in ionic solid or solution state. Na+ ion has positive charge and it must be stabilised by equal negative charge in the solid-state and by hydration in the solution state.

Why is fluorine more stable?

Fluorine is the most electronegative element because it has 5 electrons in it’s 2P shell. The optimal electron configuration of the 2P orbital contains 6 electrons, so since Fluorine is so close to ideal electron configuration, the electrons are held very tightly to the nucleus.

Why iodine is more stable than fluorine?

Compare fluorine and iodine. The size of the fluorine ion (radius: 119 pm) is much smaller than iodine (radius: 206 pm). That’s a way of expressing the greater polarizability of iodine. Low charge densities are more stable!

Is iodine more stable than fluorine?

Iodine is so much bigger than fluorine that the charge is more stable on this larger atom. That is, somehow the presence of these electronegative atoms must stabilize the conjugate base anion.

Is iodine bigger than chlorine?

Answer: it a matter of atomic size of Cl-atom and I-atom. On the other hand, atomic size of Iodine is much bigger than that of Chlorine.

Why do halogens dissolve better in organic solvents?

The halogens are much more soluble in organic solvents such as hexane than they are in water. Both hexane and the halogens are non-polar molecules, so the only intermolecular forces between them are van der Waals dispersion forces.

Why is iodine less reactive than bromine?

Iodine has 5 shells whereas bromine has 4 shells. This makes it easier for bromine to gain an electron to the outer shell when compared to iodine. Therefore, bromine is more reactive than iodine.

Why is iodine not very reactive?

Iodine is the least reactive of the halogens as well as the most electropositive, meaning it tends to lose electrons and form positive ions during chemical reactions.

Is iodine or bromine more reactive?

Bromine is more reactive than iodine, but not as reactive as chlorine.
