Diatomic Molecules And Single Elements
Elements with 2 atoms are called diatomic molecules, its because di means 2 and atomic means atoms thus 2 atoms molecule
Example Of Diatomic Molecules -: O2, This is one of the examples for diatomic molecules
There are certain elements which only have 1 atom, these types of elements come from the category from noble gases, cause elements from noble gases are very stable thus they are single
Non-Metallic Bonding
Non-metallic bonding is called as covalent bonding as it does not have any type of attraction that metals have, non metals have a different type of attraction
Covalent bonding is a bonding that occurs with non metals and it bonds by sharing electrons, when 2 molecules are in the state of electronegative it tends to share electron rather than transferring it
The bonding of covalent bonding occurs from a nonmetal to a another non metal
Main Features Of Covalent Bond
The bond is formed by a pair sharing a electron
Each atom contributes a electron at the bond
Molecules are formed when atoms like together by covalent bond
Dot And Cross Diagram
A dot-cross diagram is a diagram represented as a diagram of bonding in a molecule
Its a diagram to represent bonds of molecules
Simple Covalent Compounds
In covalent compounds bonds are made by sharing electrons between atoms
In simple molecules atoms combine to achieve a more stable arrangement
Example Of Covalent Bond -: Hydrogen chloride is a molecule that shares a single electron
1.How does covalent bonding contribute to the stability of diatomic molecules like O2 and N2?
2. Given that both chlorine and hydrogen atoms share electrons to form a molecule of HCl, explain how this satisfies the octet rule.
3. Explain the difference between ionic bonding and covalent bonding, using sodium chloride (NaCl) and water (H2O) as examples.
4. Why are covalent compounds like CO2 and H2O poor conductors of electricity?
5.How would the properties of a covalent compound change if one of the atoms involved in the bond became an ion instead of sharing electrons?
6. Can you predict the formation of a covalent bond between two atoms with different electronegativities? How does this affect the polarity of the molecule?
7. If you were to change the number of electrons shared in a covalent bond (e.g., from a single to a double bond), how would this affect the molecule's properties such as bond strength and stability?
