I believed the right answer is “A, Mixed” but i’m not too sure
Hello!
The ions that are present in solution are Ni⁺²(aq) and Cl⁻(aq)
Why?
When an ionic substance like Nickel Chloride (NiCl₂) dissolves in water, it dissociates into the individual ions that form the substance. Water molecules surround then the individual ions in a process called solvation.
It can be represented in the following chemical equation:
NiCl₂(s) → Ni⁺²(aq) + 2Cl⁻(aq)
Have a nice day!
It is likely to receive one electron from another element's atom during the creation of a bond, based on the electron configuration. The arrangement of electrons in energy levels surrounding an atomic nucleus is termed electronic configuration, or electronic structure.
Fluorine's electron configuration is
Because fluorine contains seven valence electrons, it is most likely to acquire one to create a 1-charged ion. To complete its octet, it will require one more electron. As a result, the oxidation number is 1, indicating that when fluorine interacts with another atom to form a more stable combination, it will acquire or share one electron. As a result, it is likely to acquire one electron from an atom of another element during the creation of a bond, based on the electron configuration.
I think only the second option is wrong.
Answer: Fe
Explanation: Fe (Iron) is the only element since it involves only 1 atom. The other options are compounds, since there are more than 2 atoms bonded together.
