$\boxed{{\text{C}}{\text{. C}}{{\text{F}}_4}}$ will be insoluble in water.

Further Explanation:

The bond formed due to electrostatic forces is an ionic bond. The compounds formed by the ions of the respective species are called ionic compounds. One of the species loses electrons and gets converted into cation while the other one accepts electrons and forms anion.

Covalent compound:

The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular bond. Covalent compounds or molecular compounds are those compounds which are formed by the electron sharing between two or more non-metals.

Solubility is the property of any substance that makes it soluble in other substances. It is governed by the principle “like dissolves like”.

A. NaCl is an ionic compound so it dissociates into its constituent ions on dissolving in water. Water is a polar molecule and therefore NaCl is soluble in water.

B. HCl is a polar covalent compound and water is also a polar compound so HCl is soluble in water in accordance with the principle “like dissolves like”.

C. ${\text{C}}{{\text{F}}_{\text{4}}}$ is a non-polar compound while water is a polar compound. So ${\text{C}}{{\text{F}}_{\text{4}}}$ is insoluble in water because of different nature of both substances.

D. ${\text{CuS}}{{\text{O}}_{\text{4}}}$ is an ionic compound so it dissociates into ${\text{C}}{{\text{u}}^{2 + }}$ and ${\text{SO}}_4^{2 - }$ ions on dissolving in water. Water is a polar molecule and therefore ${\text{CuS}}{{\text{O}}_{\text{4}}}$ is soluble in water.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

$^{m}_{4}x$ and $^{m}_4y$

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

$^{m}_{5}x^{-}$

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be $^{9}_{5}be^{-}$ and $^{9}_{4}be$ .

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
