Ions Quiz

What is an ion?

• An ion is an atom or molecule that has a net electrical charge due to the loss or gain of electrons.

• An ion is a type of chemical bond.

• An ion is a form of radiation.

• An ion is a type of subatomic particle.

What is the difference between a cation and an anion?

• A cation is a positively charged ion, while an anion is a negatively charged ion.

• A cation is an atom that has gained electrons, while an anion is an atom that has lost electrons.

• A cation is a negatively charged ion, while an anion is a positively charged ion.

What is ionization energy?

• The amount of energy required to remove an electron from an atom or ion in its ground state.

• The amount of energy required to move an electron from one energy level to another within an atom or ion.

• The amount of energy released when an electron is added to an atom or ion in its ground state.
