Questions and Answers

What is the condition for a compound to have a total charge of zero?

It must include only neutral atoms.

It should contain an equal number of protons and electrons.

The number of cations must equal the number of anions. (correct)

The sum of all positive charges must equal the sum of all negative charges. (correct)

Which statement correctly describes cations?

Cations have fewer protons than electrons.

Cations have no charge and exist as neutral atoms.

Cations are formed when atoms gain protons.

Cations are positively charged ions. (correct)

How do ions contribute to the conduction of electricity?

Ions must be in a gaseous state to conduct electricity.

Only cations can conduct electricity.

Electricity is conducted through the movement of neutral atoms.

Moving ions conduct electricity. (correct)

Study Notes

Atomic Structure

Atoms are neutral when they have the same number of protons and electrons.
Protons are positively charged particles in the nucleus.
Electrons are negatively charged particles that orbit the nucleus.

Ions

Ions are charged atoms.
Cations are positively charged ions formed when an atom loses electrons.
Anions are negatively charged ions formed when an atom gains electrons.
Oppositely charged ions attract each other.
Moving ions conduct electricity.
Compounds must have a neutral charge, so the number of cations and anions must balance to achieve a net charge of zero.
