what are the differences between ionic compounds and the covalent compounds for class 10
Answers
Answer:
Explanation:
Ionic compounds are formed by the transfer of electrons that are positively and negatively charged, whereas, covalent compounds are formed by sharing the electrons. 2. In an ionic compound, bonding involves a metal and nonmetal, whereas, in the covalent compound, bonding is between nonmetals.
The difference between Ionic Compounds and Covalent Compounds is their formation. The Ionic Compound is formed when there is a big difference in the electronegativity of the atoms, where the less electronegative atom loses an electron while the other gains it. It forms the ionic bond thus forming the compound. The Covalent Compound is formed by sharing the electron among the atoms to form a bond
What are Ionic Compounds?
It is a type of a chemical compound formed by transferring the electron from one atom to another. The transfer happens from the low electronegative atom to the higher electronegative atom.
This forms an ionic bond and hence ionic compound. The ionic compound is neutral, but It has two types of ions in it.
Cation: These are Positively charged Ions
Anion: These are the Negatively charged Ions
The type of formation and its bond makes the ionic compounds possess very high melting and boiling points. More importantly, they are in the solid-state.
Because Ionic compounds are in solid-state, they are also soluble in water. Further, the ionic compounds are hard and a few are brittle too.
In the solid-state, ionic compounds are not observed to conduct electricity. However, the ions start moving once it is molten or liquidized. They conduct electricity even when they are dissolved in water.
Ionic Compounds are prepared by three methods
Evaporation
Precipitation and
Freezing
It is to be understood, if the Ionic compounds are soluble in water, then it can also be evaporated to make a solid Ionic compound again.
What are Covalent Compounds?
It is a chemical compound formed by sharing the electrons with the bonded atoms. This form of sharing the electron among the atoms is called Covalent bond and thus a Covalent Compound
Covalent compounds are considered to be having a very strong Intra-molecular bond. At the same time, very little energy is required to separate the molecules too.
The Covalent compounds have relatively very low melting and boiling points. They mostly exist in the gaseous state, however liquid and solid states of covalent compounds are also available.
These compounds are never soluble in water and also do not conduct any electricity in any state. This is the prime reason, the intermolecular forces are weak between the atoms.
