Ionic and Covalent Bonds

Front

What is the charge of an oxygen atom with 8 protons and 10 electrons?

Back

O^2-

Front

How are ionic bonds formed?

Back

Through the transfer of electrons.

Front

What types of elements are involved in ionic bonds?

Back

Ionic bonds are formed between metals and non-metals.

Front

What is a valence electron?

Back

The number of electrons in the outermost shell of an atom.

Front

What is the Lewis Structure for an ionic bond between Aluminum and Oxygen?

Back

The Lewis Structure shows Aluminum donating its three valence electrons to Oxygen, resulting in Al³⁺ and O^2-.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is an example of a compound formed by ionic bonding?

Back

Sodium chloride (NaCl) is an example of an ionic compound.

Front

What is the role of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons; higher electronegativity leads to stronger ionic or covalent bonds.

Front

What is the general formula for an ionic compound?

Back

The formula is typically written as the cation followed by the anion, e.g., NaCl.

Front

What happens to the electrons in a metal during ionic bond formation?

Back

Metals lose electrons to become positively charged cations.
