Match each of the unknown ions to its appropriate description. v2+ a) a nonmetal that gained two electrons x3+ b) a nonmetal that gained three electrons y3− c) a metal that lost two electrons z2- d) a metal that lost three electrons

Answer : The correct match of the unknown ions to its appropriate description will be:

V²⁺   →    (C) A metal that lost two electrons

X³⁺   →    (D) A metal that lost three electrons

Y³⁻   →    (B) A nonmetal that gained three electrons

Z²⁻   →    (A) A nonmetal that gained two electrons

Explanation :

For the neutral atom, the number of protons and electrons are equal. But, they are unequal when the atoms present in the form of ions or the atom has some charges.

When an unequal number of electrons and protons then it leads to the formation of ionic species.

Ion : An ion is formed when an atom looses or gains electron.

For example : The neutral atom Na has equal number of protons and electrons i.e 11 but ion has unequal number of protons and electrons that means it has 11 number of protons and 10 number of electrons.

As per question,

V²⁺ is a metal that lost two electrons  and it will form a positive ion known as cation.

X³⁺ is a metal that lost three electrons  and it will form a positive ion known as cation.

Y³⁻ is a nonmetal that gained three electrons  and it will form a negative ion known as anion.

Z²⁻ is a nonmetal that gained two electrons  and it will form a negative ion known as anion.
