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 non-metal.

Front

Which element is most likely to form an ionic bond?

Back

Sodium (Na) is most likely to form an ionic bond due to its tendency to lose one electron and form a positive ion.

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 non-metal atoms.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between atoms of metallic elements, characterized by a 'sea of electrons' that are free to move.

Front

What is a compound?

Back

A compound is a substance formed by chemically combining two or more elements in definite proportions.

Front

What is a molecule?

Back

A molecule is the smallest unit of a chemical compound that retains its chemical properties, consisting of two or more atoms bonded together.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

What is a hydrogen bond?

Back

A hydrogen bond is a weak attraction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved or molten.

Front

What are the properties of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points, may be soluble in organic solvents, and do not conduct electricity.
