Answer:
V3− B) A nonmetal that gained three electrons
X− A) A nonmetal that gained one electron
Y+ C) A metal that lost one electron
Z3+ D) A metal that lost three electrons
Explanation
- Neutral atoms of elements in the periodic table react by gaining or losing electrons to attain a stable configuration according to the octet rule.
- Atoms of metals react by losing electrons to attain a stable configuration and form positively charged ions known as cations.
- For example, a neutral sodium atom, Na, would gain one electron to form a cation of sodium, Na⁺.
- Atoms of non-metals, on the other hand, react by gaining electrons to attain stable configuration and form negatively charged ions known as anions.
- For instance, a neutral chloride, Cl, atom requires to gain one electron to attain stability and form a chloride anion, Cl⁻.
An ion is formed when a chemical specie looses or gains electrons.
A positive ion refers to an ion formed by loosing electrons while a negative ion refers to an ion formed by gaining electrons. The magnitude of the positive or negative charge depends on the number of electrons lost or gained when the ion is formed.
A metal looses electrons to form positive ions while a nonmetal gains electrons to form negative ions. The following is a matching of unknown ions based on the most apt description.
- X− = A nonmetal that gained one electron
- V3− = A nonmetal that gained three electrons
- Y+ = A metal that lost one electron
- Z3+ = A metal that lost three electrons
