To match the molecules or compounds to the type of bond found between the elements, we can analyze each of them:
-
NaCl: Sodium chloride is formed between sodium (Na) and chlorine (Cl), which involves the transfer of electrons from sodium to chlorine, resulting in the formation of oppositely charged ions. This is an ionic bond.
Match: 1. NaCl : b. ionic bond
-
MgBr2: Magnesium bromide is formed between magnesium (Mg) and bromine (Br), which also involves the transfer of electrons from magnesium to the bromine atoms, forming ionic bonds. Therefore, this is also an ionic bond.
Match: 2. MgBr2 : b. ionic bond
-
CO2: Carbon dioxide consists of one carbon atom covalently bonded to two oxygen atoms. This involves the sharing of electrons between carbon and oxygen, which makes it a covalent bond.
Match: 3. CO2 : a. covalent bond
-
SO2: Sulfur dioxide consists of one sulfur atom covalently bonded to two oxygen atoms. Similar to CO2, this compound also involves the sharing of electrons, resulting in covalent bonds.
Match: 4. SO2 : a. covalent bond
In summary, here are the matches:
- NaCl : b. ionic bond
- MgBr2 : b. ionic bond
- CO2 : a. covalent bond
- SO2 : a. covalent bond
