Question

Classify the following descriptions according to whether they describe sodium atom, sodium ion, or neither.

Answer Bank A large group of these is shiny and malleable Attracts cations Forms a crystal lattice when paired with an anion Exhibits electrostatic attraction to CI- Has the Lewis structure Nat Repels cations Is unstable and highly reactive Has the Lewis structure Na Has the Lewis structure Nat Has the Lewis structure Na

Answer 1

coses electron. N a sodium is a metal having atomic number of ff. . It has one elechon en valence shell, and hence to make itsely stable to achieve nearest noble gas configuration of neon, it loses one eleton to come electronegative element and makes an ionic koud. : 1. Na Sedium medal casion D A large gedup is shiny and malleable is a property of sodium I u to pure form be, sodirum atom, 2) If it attract ious git means it is in the form of Na wch aitzact -UE jozu. Sodium ion 3) It forms a crystal lattice when paired with awon. Sodium ion lig. Nat + Clan Nall 4) Exhibit electrostatic altraction to climeans it is Nat Socliumion 5) Has Lewis structure Nat --- sodium ion 6) Repels cation because it has the charge (Nat) sodium ion 7) Sodium metal in pelre form is clustable and wiguly. reactive. It means it is sodium atom 8) Has the lewis structure na means it is unreacted form iz, sodiuen atom
