Ionic and Metallic Bonding

Front

What is the primary difference between ionic and metallic bonding?

Back

Ionic bonding involves the transfer of electrons from one atom to another, resulting in the formation of charged ions, while metallic bonding involves the sharing of free electrons among a lattice of metal atoms.

How many valence electrons does potassium (K) have?

Back

Potassium (K) has 1 valence electron.

Front

What is the electron configuration of a fluoride ion (F^-)?

Back

The electron configuration of a fluoride ion (F^-) is 1s² 2s² 2p⁶, indicating it has 8 valence electrons.

What is the charge of an arsenide ion (As^3-)?

Back

The charge of an arsenide ion (As^3-) is -3.

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 have specific properties.

Front

Which of the following is NOT an alloy: bronze, steel, copper?

Back

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

Front

What type of bond is formed between sodium (Na) and chlorine (Cl) in sodium chloride (NaCl)?

Back

An ionic bond is formed between sodium (Na) and chlorine (Cl) in sodium chloride (NaCl).

Front

What is the role of valence electrons in bonding?

Back

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

Front

How do metallic bonds contribute to the properties of metals?

Back

Metallic bonds allow for the delocalization of electrons, which contributes to properties such as electrical conductivity, malleability, and ductility.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
