Chemical Bonding Flashcard

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, typically between a metal and a nonmetal, where the metal donates electrons to the nonmetal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, typically between nonmetals.

Front

What does the symbol above an atom in a Lewis structure indicate?

Back

The symbol indicates the relative attraction of electrons to that atom compared to other atoms in the structure.

Front

Under what conditions can ionic compounds conduct electricity?

Back

Ionic compounds can conduct electricity when they are melted or dissolved in water, allowing the ions to move freely.

Front

How many electrons are shared in a double covalent bond?

Back

In a double covalent bond, four electrons are shared between the two atoms.

Front

Which bond has the shortest bond length: C—C, H—H, O—H, or H—Cl?

Back

H—H has the shortest bond length among the given options.

Front

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion, formed when an atom loses one or more electrons, while an anion is a negatively charged ion, formed when an atom gains one or more electrons.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a Lewis structure?

Back

A Lewis structure is a diagram that represents the bonding between atoms and the lone pairs of electrons in a molecule.
