What are metallic bonds?

Back

Metallic bonds are formed by the attraction between positively charged metal ions and a 'sea' of delocalized electrons that are free to move around, allowing metals to conduct electricity and heat.

What is the charge of an ionic compound formed from magnesium and chlorine?

Back

The charge of the ionic compound formed from magnesium and chlorine is 0, as magnesium loses two electrons to become Mg²⁺ and chlorine gains one electron to become Cl⁻, resulting in a neutral compound (MgCl₂).

Front

What is the Octet Rule?

Back

The Octet Rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their valence shell, achieving a stable electron configuration.

What does it mean for a material to be ductile?

Back

A ductile material is one that can be drawn out into a thin wire without breaking.

Front

What is a property of ionic compounds?

Back

Ionic compounds typically have a crystalline structure, high melting and boiling points, and conduct electricity when dissolved in water.

Front

What is the difference between malleability and ductility?

Back

Malleability is the ability of a material to be hammered or pressed into shape without breaking, while ductility is the ability to be stretched into a wire.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

What is the significance of the 'sea of electrons' in metallic bonding?

Back

The 'sea of electrons' allows for the conductivity of electricity and heat in metals, as these electrons can move freely throughout the metal structure.

Front

What is a characteristic property of metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.

Front

What happens to electrons during the formation of ionic bonds?

Back

During the formation of ionic bonds, one atom loses electrons to become a positively charged ion, while another atom gains those electrons to become a negatively charged ion.
