Question

Match each of the unknown ions to its appropriate description. Match Term Definition V3− A) A nonmetal that gained one electron X− B) A nonmetal that gained three electrons Y+ C) A metal that lost one electron Z3+ D) A metal that lost three electrons

Answer 1

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⁻.
