State whether the following statement is true or false:
$A$ group of atoms carrying a charge is called bivalent ions.
$A$ group of atoms carrying a charge is called bivalent ions.
(B) The statement is False.
$A$ group of atoms carrying a charge is known as a polyatomic ion,not a bivalent ion.
$A$ bivalent ion refers to an atom or ion that has a valency of $2$,meaning it can form two chemical bonds (e.g.,$Mg^{2+}$ or $Ca^{2+}$).
