What is ionic bonding?

Back

Ionic bonding is the electrostatic attraction between oppositely charged ions, typically formed when an electron is transferred from a metal to a non-metal.

Front

What is covalent bonding?

Back

Covalent bonding involves the sharing of electron pairs between atoms, usually between non-metals.

Front

What are delocalized electrons?

Back

Delocalized electrons are electrons that are not associated with a single atom or bond and can move freely within a structure, often found in metals and some molecular compounds.

Front

What is the significance of conductivity in substances?

Back

Conductivity indicates how well a substance can conduct electricity, which is influenced by the presence of free-moving charged particles, such as ions or delocalized electrons.

Front

What is a molecular covalent compound?

Back

A molecular covalent compound is formed when two or more non-metal atoms share electrons, resulting in molecules, such as H2S.

What is the difference between brittle and ductile materials?

Back

Brittle materials break easily under stress without significant deformation, while ductile materials can be stretched or deformed without breaking.

Front

What is the general property of metals regarding conductivity?

Back

Metals are generally good conductors of electricity due to the presence of delocalized electrons that can move freely.

Front

What is the state of matter for most covalent compounds at room temperature?

Back

Most covalent compounds are gases or liquids at room temperature, with some exceptions being solid.
