remember... ionic bond covalent bond between a metal and non - metal (m + nm) between a non - metal and non - metal (nm + nm) part 1: determine if the elements in the following compounds are metals or non - metals. describe the type of bonding that occurs in the compound. compound element 1 (metal or non - metal?) element 2 (metal or non - metal?) bond type no2 n = non - metal o = non - metal covalent nacl so2 p4 mgbr2 cao h2o k2o alf3 o2 o = nm o = nm covalent cucl2 no2 co2 hf rb2s rb = metal s = nm ionic nbr3 fe2o3 ccl4 c = nm cl = nm covalent
Step1: Recall metal - non - metal classification
Metals are typically found on the left - hand side and middle of the periodic table, non - metals on the right.
Step2: Recall bonding rules
Ionic bonds form between a metal and a non - metal, covalent bonds form between non - metals.
Step3: Analyze NaCl
Na (sodium) is a metal, Cl (chlorine) is a non - metal. So, the bond type is ionic.
Step4: Analyze SO₂
S (sulfur) is a non - metal, O (oxygen) is a non - metal. So, the bond type is covalent.
Step5: Analyze P₆
P (phosphorus) is a non - metal. Since it's a non - metal compound, the bond within it is covalent.
Step6: Analyze MgBr₂
Mg (magnesium) is a metal, Br (bromine) is a non - metal. So, the bond type is ionic.
Step7: Analyze CaO
Ca (calcium) is a metal, O (oxygen) is a non - metal. So, the bond type is ionic.
Step8: Analyze H₂O
H (hydrogen) is a non - metal, O (oxygen) is a non - metal. So, the bond type is covalent.
Step9: Analyze K₂O
K (potassium) is a metal, O (oxygen) is a non - metal. So, the bond type is ionic.
Step10: Analyze AlF₃
Al (aluminum) is a metal, F (fluorine) is a non - metal. So, the bond type is ionic.
Step11: Analyze O₂
O (oxygen) is a non - metal. The bond within O₂ is covalent.
Step12: Analyze CuCl₂
Cu (copper) is a metal, Cl (chlorine) is a non - metal. So, the bond type is ionic.
Step13: Analyze NO₂
N (nitrogen) is a non - metal, O (oxygen) is a non - metal. So, the bond type is covalent.
Step14: Analyze CO₂
C (carbon) is a non - metal, O (oxygen) is a non - metal. So, the bond type is covalent.
Step15: Analyze HF
H (hydrogen) is a non - metal, F (fluorine) is a non - metal. So, the bond type is covalent.
Step16: Analyze Rb₂S
Rb (rubidium) is a metal, S (sulfur) is a non - metal. So, the bond type is ionic.
Step17: Analyze NBr₃
N (nitrogen) is a non - metal, Br (bromine) is a non - metal. So, the bond type is covalent.
Step18: Analyze Fe₂O₃
Fe (iron) is a metal, O (oxygen) is a non - metal. So, the bond type is ionic.
Step19: Analyze CCl₄
C (carbon) is a non - metal, Cl (chlorine) is a non - metal. So, the bond type is covalent.
