Question 3 • TN-Physical Science SC 26-27 (For Credit)

Which statements describe polyatomic ions? Check all that apply.Polyatomic ions have many charges.Polyatomic ions have one overall charge.Polyatomic ions repel other ions to form ionic bonds.Polyatomic ions attract other ions to form ionic bonds.Polyatomic ions are made up of only one type of atom.Polyatomic ions are made up of two or more types of atoms.

Answer
A
Polyatomic ions have many charges.
B
Polyatomic ions have one overall charge.
C
Polyatomic ions repel other ions to form ionic bonds.
D
Polyatomic ions attract other ions to form ionic bonds.
E
Polyatomic ions are made up of only one type of atom.
F
Polyatomic ions are made up of two or more types of atoms.

Explanation

A polyatomic ion is a group of atoms with one net, or overall, charge, so B is correct. It can form an ionic bond by attracting an oppositely charged ion, making D correct; like charges repel rather than form the bond. Polyatomic ions contain two or more types of atoms, so F is also correct.
