Ionic, Covalent & Metallic

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, where electrons are delocalized and shared among a lattice of metal cations, allowing metals to conduct electricity and be malleable.

Front

Which statement describes ionic compounds?

Back

Ionic compounds are formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).

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 the main characteristic of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points due to the strong electrostatic forces between the ions.

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.

Front

What does it mean for a substance to be malleable?

Back

Malleability is the ability of a substance, particularly metals, to be hammered or pressed into thin sheets without breaking.

Front

What is the significance of a full valence shell in bonding?

Back

Atoms bond to achieve a full valence shell, which provides stability and lowers the energy of the atom.

Front

What are polyatomic ions?

Back

Polyatomic ions are ions that consist of two or more atoms bonded together, which carry a net charge due to the loss or gain of electrons.

Front

What is the typical state of covalent compounds at room temperature?

Back

Covalent compounds can exist as solids, liquids, or gases at room temperature.

Front

What is the term for the ability of metals to conduct electricity?

Back

The ability of metals to conduct electricity is due to the presence of delocalized electrons that can move freely throughout the metal.
