Ions EXAM CP

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 are cations?

Back

Cations are positively charged ions that are formed when an atom loses one or more electrons.

Front

What are anions?

Back

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

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What do valence electrons determine?

Back

Valence electrons determine an atom's chemical properties and its ability to bond with other atoms.

Front

How do non-metals typically behave in terms of electrons?

Back

Non-metals tend to gain valence electrons to achieve a full outer shell.

Front

What is an electron dot structure?

Back

An electron dot structure is a representation of the valence electrons of an atom, using dots around the element's symbol.

Front

What does each dot in an electron dot structure represent?

Back

Each dot represents a valence electron.

Front

What happens to an atom when it gains electrons?

Back

When an atom gains electrons, it becomes a negatively charged ion, known as an anion.

Front

What happens to an atom when it loses electrons?

Back

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