Question

worksheet: chemical bonding - ionic & covalent!
remember...
ionic bond between a metal and non - metal (m + nm)
covalent bond between a non - metal and non - metal (nm + nm)
determine if the elements in the following compounds are metals or non - metals. describe the type of bonding that occurs in the compound.

Explanation:

Step1: Identify metal and non - metal

• For \(NaCl\): \(Na\) (sodium) is a metal, \(Cl\) (chlorine) is a non - metal.
• For \(SO_{2}\): \(S\) (sulfur) is a non - metal, \(O\) (oxygen) is a non - metal.
• For \(PI_{3}\): \(P\) (phosphorus) is a non - metal, \(I\) (iodine) is a non - metal.
• For \(MgBr_{2}\): \(Mg\) (magnesium) is a metal, \(Br\) (bromine) is a non - metal.
• For \(CaO\): \(Ca\) (calcium) is a metal, \(O\) (oxygen) is a non - metal.
• For \(H_{2}O\): \(H\) (hydrogen) is a non - metal, \(O\) (oxygen) is a non - metal.
• For \(K_{2}O\): \(K\) (potassium) is a metal, \(O\) (oxygen) is a non - metal.
• For \(AlF_{3}\): \(Al\) (aluminum) is a metal, \(F\) (fluorine) is a non - metal.
• For \(O_{2}\): \(O\) (oxygen) is a non - metal (diatomic non - metal molecule).
• For \(CuCl_{2}\): \(Cu\) (copper) is a metal, \(Cl\) (chlorine) is a non - metal.
• For \(NO_{2}\): \(N\) (nitrogen) is a non - metal, \(O\) (oxygen) is a non - metal.
• For \(CO_{2}\): \(C\) (carbon) is a non - metal, \(O\) (oxygen) is a non - metal.
• For \(HF\): \(H\) (hydrogen) is a non - metal, \(F\) (fluorine) is a non - metal.
• For \(Rb_{2}S\): \(Rb\) (rubidium) is a metal, \(S\) (sulfur) is a non - metal.
• For \(NBr_{3}\): \(N\) (nitrogen) is a non - metal, \(Br\) (bromine) is a non - metal.
• For \(Fe_{2}O_{3}\): \(Fe\) (iron) is a metal, \(O\) (oxygen) is a non - metal.
• For \(CCl_{4}\): \(C\) (carbon) is a non - metal, \(Cl\) (chlorine) is a non - metal.

Step2: Determine bond type

• Ionic bond: between a metal and a non - metal (\(M + NM\)).
• Covalent bond: between non - metals (\(NM+NM\)).
