Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming chemical bonds.

Front

What is the formula unit of aluminum oxide?

Back

The formula unit of aluminum oxide is Al₂O₃.

Front

What is the charge of a potassium ion when it achieves noble-gas electron configuration?

Back

The charge of a potassium ion when it achieves noble-gas electron configuration is K⁺.

Front

What is a characteristic physical property of ionic compounds in their solid state?

Back

Ionic compounds in their solid state have strong attractive forces between ions, making them brittle.

Front

What is the significance of Lewis structures in chemistry?

Back

Lewis structures help visualize the arrangement of valence electrons around atoms in a molecule, aiding in understanding bonding.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

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

Back

The number of valence electrons can be determined from the group number of the element in the periodic table.

Front

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion, while an anion is a negatively charged ion.

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 role of electronegativity in ionic bonding?

Back

Electronegativity is the tendency of an atom to attract electrons; in ionic bonding, a highly electronegative atom attracts electrons from a less electronegative atom.
