metallic bonding

Front

What is metallic bonding?

Back

Metallic bonding is the electrostatic attraction between positively charged metal ions and the delocalized electrons that are free to move throughout the structure.

Front

What is an alloy?

Back

An alloy is a mixture of two or more elements, where at least one is a metal, designed to enhance certain properties such as strength and resistance to corrosion.

Front

Which of the following is NOT an alloy?

Back

Copper is not an alloy; it is a pure metal.

Front

What is an ion?

Back

An ion is an atom that has gained or lost electrons, resulting in a net electrical charge.

Front

What is the order of metallic bond strength from strongest to weakest?

Back

The order is Mg > Na > K > Rb.

Front

How do covalent bonds form?

Back

Covalent bonds form by sharing valence electrons between atoms.

Front

Why are alloys generally used to make everyday objects?

Back

Alloys are often stronger and less active than pure metals, making them more suitable for various applications.

Front

What is the difference between a pure metal and an alloy?

Back

A pure metal consists of only one type of atom, while an alloy is a combination of different elements, often resulting in improved properties.

Front

What is the role of delocalized electrons in metallic bonding?

Back

Delocalized electrons allow metals to conduct electricity and heat, and contribute to the malleability and ductility of metals.

Front

What is the significance of the melting point in metals and alloys?

Back

Alloys typically have higher melting points than pure metals, which can make them more suitable for high-temperature applications.
