Question

Ionic Polar Covalent Nonpolar Covalent
Iodine, I + Iodine, I

Indium, In + Fluorine, F

Hydrogen, H + Bromine, Br

Calcium, Ca + Chlorine, Cl

Answer 1

To classify the types of bonding between the pairs of elements you've provided, we can look at their electronegativity differences and the type of elements involved (metal, nonmetal, etc.). Here's the classification for each pair:

1. Iodine, I + Iodine, I

   • Type of Bonding: Nonpolar Covalent
   • Reason: Both atoms are identical nonmetals, leading to equal sharing of electrons.

2. Indium, In + Fluorine, F

   • Type of Bonding: Polar Covalent
   • Reason: Indium is a metal with a relatively low electronegativity, and fluorine is a highly electronegative nonmetal. This difference creates a polar bond due to unequal sharing of electrons.

3. Hydrogen, H + Bromine, Br

   • Type of Bonding: Polar Covalent
   • Reason: Hydrogen is a nonmetal with a lower electronegativity compared to bromine, which is also a nonmetal but has a higher electronegativity. This gives rise to a polar bond.

4. Calcium, Ca + Chlorine, Cl

   • Type of Bonding: Ionic
   • Reason: Calcium is a metal, and chlorine is a nonmetal. Calcium tends to lose electrons, while chlorine tends to gain electrons, resulting in the formation of an ionic bond.

Here's the completed classification:

| Pair | Ionic | Polar Covalent | Nonpolar Covalent | |--------------------------|-------|-----------------|--------------------| | Iodine, I + Iodine, I | | | ✓ | | Indium, In + Fluorine, F | | ✓ | | | Hydrogen, H + Bromine, Br| | ✓ | | | Calcium, Ca + Chlorine, Cl| ✓ | | |
