Solution

Solution Steps

Step 1: Determine Compound Formation for $\mathrm{Li}^{1+}$

$\mathrm{Li}^{1+}$ is a cation with a single positive charge.
It can form ionic compounds by pairing with anions that have a negative charge.
However, the question does not provide a specific anion to pair with $\mathrm{Li}^{1+}$, so we cannot determine a specific compound.

Step 2: Determine Compound Formation for $\mathrm{Ca}^{2+}$ and $\mathrm{F}^{1-}$

$\mathrm{Ca}^{2+}$ is a cation with a charge of $+2$.
$\mathrm{F}^{1-}$ is an anion with a charge of $-1$.
To form a neutral compound, two $\mathrm{F}^{1-}$ ions are needed to balance the charge of one $\mathrm{Ca}^{2+}$ ion.
The resulting compound is $\mathrm{CaF}_2$.

Step 3: Determine Compound Formation for $\mathrm{O}^{2-}$

$\mathrm{O}^{2-}$ is an anion with a charge of $-2$.
It can form ionic compounds by pairing with cations that have a positive charge.
However, the question does not provide a specific cation to pair with $\mathrm{O}^{2-}$, so we cannot determine a specific compound.
