Interpretation:
Type of bonding is to be filled in the given table.
Concept introduction:
There is a force of attraction between atoms which keeps them together. This force of attraction is called chemical bond.
- Ionic bond
- Molecular covalent bond
- Metallic bond
- Network covalent bond
Answer to Problem SV4RQ
The following table shows the type of bond.
Dissolves | Does not dissolve | |
Conducts | Ionic bond | Metallic bond |
Does not conduct | Molecular covalent | Network covalent |
Explanation of Solution
Given information:
The following table is given.
Dissolves | Does not dissolve | |
Conducts | ||
Does not conduct |
- Ionic bond -. The valence electrons are transferred from metal atom to nonmetal atom. Compounds with ionic bonds can conduct electricity when dissolved in water as the metal and nonmetal ions are free to move in solution.
- Metallic bond - The atoms are bonded by the attraction between the positively charged nucleus of one atom and negatively charged electrons of other atom. The valence electrons are free to move about in substance so the compounds can conduct electricity. Metallic substances do not dissolve in water.
- Molecular covalent bond -Here both the atoms share the valence electrons between them. Compounds with such bonds cannot conduct electricity because charges cannot move freely in it. Some substances with these bonds dissolve in water while some do not dissolve.
- Network covalent - These compounds do not conduct electricity and do not dissolve in water. Here, the valence electrons are shared throughout the entire substance. They form a highly extended network and so electrons cannot move freely in it.
There are four models of bonding. Each model has a different property due to which the compounds are able to conduct electricity and dissolve in water to form solutions.
