Question

3. Determine if the bond between atoms in each example below is nonpolar covalent, polar covalent, or ionic a. H-H b. P-Cl c. F-F d. Na-Br e. N-F f. Mg-O g. C-H h. H-Cl

Answer 1

Answer:

H-H bond : covalent bond

P-Cl bond : polar covalent bond

F-F bond : non polar covalent bond

Na - Br : ionic bond

N - F : tunable covalent bond

Mg - O : ionic bond

C-H : hydrogen bond

H-Cl : covalent bond

Answer 2

The bond between atoms in each example below can be given as:

a. H-H : Nonpolar covalent bond

b. P-Cl : Polar covalent bond

c. F-F : Nonpolar covalent bond

d. Na-Br : Ionic bond

e. N-F : Polar covalent bond

f. Mg-O : Ionic bond

g. C-H : Covalent bond

h. H-Cl: Ionic bond

Explanation:

• A covalent bond is formed by an equal sharing of electrons between two atoms.
• A covalent bond can be of two types: Polar and Non-polar.
• A polar covalent bond is formed when two atoms of different electronegativities share electrons.
• A non-polar covalent bond is formed when two atoms of the same electronegativities share electrons in a covalent bond.
• An ionic bond is formed by the transfer of electrons from an atom having a tendency to lose electrons to an atom having a tendency to gain electrons.
