Science 9 Unit 6: Chemical Bonding Review

Front

What is a cation?

Back

A cation is a positively charged ion formed by losing one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion formed by gaining one or more electrons.

Front

What is the overall charge of an ionic compound?

Back

The overall charge of an ionic compound is 0, meaning it is neutral.

Front

What type of ion do metals usually form?

Back

Metals usually form cations.

Front

What is the name of the ion formed when sulfur (S) gains electrons?

Back

The ion formed is called a sulfide ion.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons between atoms, while covalent bonds involve the sharing of 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 a chemical bond?

Back

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds.

Front

What is the role of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in partial charges.
