Ionic Compounds

Front

What are electrons in the outermost energy level called?

Back

Valence electrons are the electrons in the outermost energy level of an atom, which are involved in chemical bonding.

Front

If my charge becomes 2+, what does that say about me?

Back

If an atom has a charge of 2+, it means it has lost 2 electrons.

Front

What is the chemical formula for an ionic compound of potassium and oxygen?

Back

The chemical formula for the ionic compound of potassium and oxygen is K₂O.

Front

What happens to an atom when it gains electrons?

Back

When an atom gains electrons, it becomes negatively charged.

Front

How do sodium (Na) and fluorine (F) bond together?

Back

Sodium (Na) and fluorine (F) bond together to form NaF.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

What are cations and anions?

Back

Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining 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 is the significance of the periodic table in understanding ionic compounds?

Back

The periodic table helps predict how elements will bond based on their position, which indicates their valence electrons.

Front

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

Back

The formula for the ionic compound formed between magnesium and chlorine is MgCl₂.
