Ions and Ionic Bonding

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 charge of a cation?

Back

A cation is a positively charged ion, formed when an atom loses one or more electrons.

Front

What is the charge of an anion?

Back

An anion is a negatively charged ion, formed when an atom gains one or more electrons.

Front

How do you represent a sulfate ion?

Back

The sulfate ion is represented as SO₄²⁻.

Front

What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed between metals and nonmetals.

Front

What happens to electrons during ionic bonding?

Back

In ionic bonding, electrons are transferred from one atom to another, resulting in the formation of cations and anions.

Front

What is the Lewis Dot Diagram?

Back

The Lewis Dot Diagram is a representation of the valence electrons of an atom, shown as dots around the element's symbol.

Front

How many valence electrons does aluminum have?

Back

Aluminum has 3 valence electrons.

Front

What is the formula for the ionic compound formed between sodium and chlorine?

Back

The formula is NaCl, representing sodium chloride.

Front

What is the significance of the octet rule in ionic bonding?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.
