Ionic and covalent bonds

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed by the sharing of electrons between atoms.

Front

How do ionic bonds form?

Back

Ionic bonds form when one atom transfers electrons to another atom, resulting in the formation of charged ions that attract each other.

Front

What are valence electrons?

Back

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

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.

Front

Which types of elements typically form ionic bonds?

Back

Ionic bonds typically form between metals and nonmetals.

Front

What role do group numbers on the periodic table play in determining valence electrons?

Back

Group numbers indicate the number of valence electrons in the outermost shell of the elements in that group.

Front

What happens to an atom with 1 valence electron when it reacts?

Back

An atom with 1 valence electron is more likely to lose that electron to achieve a full outer shell.

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

How can you determine the number of valence electrons in an element?

Back

You can determine the number of valence electrons by looking at the group number of the element on the periodic table.

Front

What is an example of a covalent compound?

Back

An example of a covalent compound is water (H2O), where hydrogen and oxygen share electrons.
