Ionic/Covalent Compounds Weekly Assessment

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

Front

What is a covalent compound?

Back

A covalent compound is a chemical compound formed by the sharing of electrons between atoms, usually between nonmetals.

Front

What is the charge of a neutral atom?

Back

A neutral atom has no overall charge, meaning the number of protons equals the number of electrons.

Front

What are electrons?

Back

Electrons are subatomic particles with a negative charge that are involved in chemical bonding.

Front

What happens to electrons in ionic bonding?

Back

In ionic bonding, electrons are transferred from one atom to another, resulting in the formation of positive and negative ions.

Front

What is the significance of 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, leading to stability.

Front

What is a positive ion?

Back

A positive ion, or cation, is an atom that has lost one or more electrons, resulting in a net positive charge.

Front

What is a negative ion?

Back

A negative ion, or anion, is an atom that has gained one or more electrons, resulting in a net negative charge.

Front

What is the formula for sodium chloride?

Back

The formula for sodium chloride is NaCl, which is an example of an ionic compound.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between oppositely charged ions, while covalent bonds involve the sharing of electrons between atoms.
