Chapter U1, Problem 6RE

Interpretation Introduction

Interpretation:

How to use periodic table to predict the type of bond between two atoms is to be explained.

Concept introduction:

There is a force of attraction between atoms which keeps them together. This force of attraction is called chemical bond. A periodic is a storehouse of information about elements.

Answer to Problem 6RE

From the periodic table, one can find out if the element in the compound is a metal or a nonmetal or both.

• Ionic bonding is found in compounds made of a metal and a nonmetal
• Metallic bonding is found in compounds made of only metals
• Network covalent bonding is found in compounds made of only nonmetals
• Molecular covalent bonding is found in compounds made of only nonmetals

Explanation of Solution

There are four types of bonds:

1. Ionic bond
2. Molecular covalent bond
3. Metallic bond
4. Network covalent bond

The periodic table is important in finding out the type of bonding possible between atoms. From the table one can find out if the element in the compound is a metal or a nonmetal or both. Depending upon the constitution of compound, the type of bonding can be predicted.

• Ionic bonding is found in compounds made of a metal and a nonmetal.
• Metallic bonding is found in compounds made of only metals.
• Network covalent bonding is found in compounds made of only nonmetals.
• Molecular covalent bonding is found in compounds made of only nonmetals.

The main difference between network and molecular covalent bonding is that in molecular covalent bonding, the covalent bond is formed between two atoms by sharing of electrons. In network covalent bonding, the cluster of atoms form a continuous network of atoms bonded together via covalent bonds.

Conclusion

There are four models of bonding. Each model has a different property. The periodic table is very helpful in providing information about the type of bonding possible between atoms of different elements.
