Explanation:
Hello,
In this case, for the dissociation of calcium fluoride:
The equilibrium expression is:
In such a way, via the ICE procedure, including an initial concentration of calcium of 0.01 M (due to the calcium nitrate solution), the reaction extent is computed as follows:
Thus, the molar solubility equals the reaction extent , therefore:

For 7A(17) :
Electronic configuration
So, there are 5 unpaired electrons present in group 7A(17).
<h3>What are Unpaired Electrons?</h3>- An unpaired electron is an electron that doesn't form part of an electron pair when it occupies an atom's orbital in chemistry.
- Each of an atom's three atomic orbitals, designated by the quantum numbers n, l, and m, has the capacity to hold a pair of two electrons with opposing spins.
- Unpaired electrons are extremely uncommon in chemistry because an object carrying an unpaired electron is typically quite reactive. This is because the production of electron pairs, whether in the form of a chemical bond or as a lone pair, is frequently energetically advantageous.
- They play a crucial role in describing reaction pathways even though they normally only appear momentarily during a reaction on a thing called a radical in organic chemistry.
