Questions and Answers

What is metallic bonding primarily a result of?

Covalent bonding between metal atoms

Ionic bonding between metal atoms

Electrostatic attractive force between conduction electrons and positively charged metal ions (correct)

Van der Waals forces between metal atoms

What properties of metals does metallic bonding account for?

High reactivity, low density, and translucency

Malleability, low electrical conductivity, and dull appearance

Brittleness, low melting point, and insulating properties

Strength, ductility, thermal and electrical resistivity and conductivity, opacity, and lustre (correct)

In what form are the conduction electrons in metallic bonding?

Shared equally between metal atoms

Bound to specific metal ions

Electron cloud of delocalized electrons (correct)

Localized around individual metal ions

Explain ionic bonding and the type of atoms involved in it.

Ionic bonding involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities. It primarily occurs between a metal atom (cation) and a nonmetal atom (anion) to achieve a full valence shell for both atoms. Signup and view all the answers

What are ions and how are they formed?

Ions are atoms (or groups of atoms) with an electrostatic charge. Atoms that gain electrons make negatively charged ions (anions), while atoms that lose electrons make positively charged ions (cations). Signup and view all the answers

Differentiate between electrovalence and covalence.

Electrovalence refers to the transfer of electrons resulting in ionic bonding, while covalence involves the sharing of electrons between atoms in a molecule. Signup and view all the answers

Provide examples of complex ions formed through ionic bonding.

Complex ions such as NH+4 (ammonium ion) and SO2−4 (sulfate ion) are formed through ionic bonding. Signup and view all the answers

Explain the process that results in an ionic bond.

An ionic bond results from the transfer of electrons from a metal to a non-metal to obtain a full valence shell for both atoms. Signup and view all the answers
