Topic 4: Chemical bonding
6. Covalent Bonding: Recalling concept facts and definitions
1. A Covalent bond is formed between atoms of
1) Two nonmetals 3) A metal and a nonmetal
2) Two metals 4) A metal and a metalloid
2. Covalent bonding occurs when electrons are
1) Transferred from a metallic atom to a nonmetallic atom
2) Transferred from a nonmetallic atom to a metallic atom
3) Shared between metallic atoms
4) Shared between nonmetallic atoms
3. When two atoms form a covalent bond, the electronegativity difference between these two atoms is
generally 3) Exactly zero

2) Must always be unequal
4) Can be equal or unequal
5. Which list includes only types of covalent bonding?

4) Network solids, metallic, and nonpolar
7. Polar and Nonpolar Covalent bonding: Recalling concept facts and definitions
1. The bonding in polar covalent bonding occurs when 3) Two different metals share electrons
1) Two of the same metals share electrons
2) Two of the same nonmetals share electrons 4) Two different nonmetals share electrons
2. Sharing of electrons in polar covalent bonding is usually
1) Unequal between two different nonmetals
3) Equal between two different nonmetals
2) Unequal between two of the same nonmetals 4) Equal between two of the same nonmetals
3. The bonding in nonpolar covalent bonding occurs when
1) Two of the same metals share electrons 3) Two different metals share electrons
2) Two of the same nonmetals share electrons 4) Two different nonmetals share electrons
4. Sharing in nonpolar covalent bonding is usually
1) Unequal between two different nonmetals 3) Equal between two of the same nonmetals
2) Unequal between two of the same nonmetals 4) Equal between two different nonmetals
5. When two atoms form a polar covalent bond, the electronegativity difference between these two
atoms is generally
1) Exactly zero 3) Less than 1.7 but greater than zero
2) Below Zero
4) Greater 1.7
6. When two atoms formed a nonpolar covalent bond, the electronegativity difference between these
two atoms is usually
1) About zero 3) Exactly 1.7
2) Below Zero 4) Greater 1.7
