Ions and Isotopes

Front

What charge do anions have?

Back

Anions have a negative charge (-).

Front

How many valence electrons does Chlorine [Cl] in group #17 have?

Back

Chlorine has 7 valence electrons.

Front

What charge do cations have?

Back

Cations have a positive charge (+).

Front

Which particles are NOT found inside the nucleus of an atom?

Back

Electrons are not found inside the nucleus.

Front

What happens to electrons when anions are formed?

Back

Anions gain electrons.

Front

What is an ion?

Back

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

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions (loss of electrons), while anions are negatively charged ions (gain of electrons).

Front

What is an isotope?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.

Front

How do isotopes of the same element differ?

Back

Isotopes differ in mass number due to the different number of neutrons.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.
