Atomic Structure and Ions

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

Why do atoms form ions?

Back

Atoms form ions to achieve stability, often by gaining or losing electrons.

Front

What are neutrons?

Back

Neutrons are neutral subatomic particles located in the nucleus of an atom.

Front

What are anions?

Back

Anions are negatively charged ions formed when an atom gains one or more electrons.

Front

What happens to an atom when it loses electrons?

Back

When an atom loses electrons, it becomes a positively charged ion.

Front

What is the charge of protons?

Back

Protons have a positive charge.

Front

What is the charge of electrons?

Back

Electrons have a negative charge.

Front

What is the role of neutrons in an atom?

Back

Neutrons help stabilize the nucleus by offsetting the repulsive forces between protons.

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, while anions are negatively charged ions.
