Welcome class! Today, we'll talk about covalent bonding. Who can explain what happens in a covalent bond?
Is it when atoms share electrons?
Exactly! Covalent bonds are formed by the sharing of electrons between non-metal atoms. This is different from ionic bonds, which involve the transfer of electrons.
So, do both atoms become stable when they share electrons?
Yes! By sharing electrons, both atoms can achieve a full outer shell of electrons, following the octet rule. This helps them to be more stable.
Let's discuss the types of covalent bonds. What would happen if two atoms share more than one pair of electrons?
They form a double or triple bond, right?
Correct! When two pairs are shared, it's a double bond. If three pairs are shared, it's a triple bond. Can anyone give me an example of a molecule with a double bond?
Oxygen! In O2, the two oxygen atoms share two pairs of electrons.
Great example! So remember, the more pairs of electrons shared, the stronger the bond.
Now, why do you think covalent bonds are so important?
Because they help form stable molecules?
Exactly! Without covalent bonds, many compounds we see in chemistry wouldn't exist. Can you name a few examples?
Water, CO2, and ammonia!
Right! These compounds are essential for life and involve covalent bonding.
Covalent sharing makes you and I, Stability through pairs, oh my oh my!
Once upon a time, two atoms met and decided to share their treasures, forming a bond that made both of them stable and happy.

A type of chemical bond formed by the sharing of electron pairs between atoms, typically between non-metals.
A covalent bond in which one pair of electrons is shared between two atoms.
A covalent bond in which two pairs of electrons are shared between two atoms.
A covalent bond in which three pairs of electrons are shared between two atoms.
The principle that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving stability.
Covalent bonding involves the sharing of electrons between non-metal atoms, forming stable molecules.
Covalent bonding is characterized by the sharing of electrons, which can form single, double, or triple bonds depending on the number of electron pairs shared between atoms. This type of bonding typically occurs between non-metals, allowing each atom to achieve a stable electron configuration.
Covalent bonding is a fundamental concept in chemistry that describes how non-metal atoms bond by sharing pairs of electrons. In a covalent bond, each atom contributes one or more electrons, allowing them to attain a stable electron configuration similar to that of noble gases. Bonds may be classified as single, double, or triple depending on how many pairs of electrons are shared. For example, in the hydrogen molecule (H2), two hydrogen atoms share one pair of electrons to achieve stability. This section also emphasizes the role of shared electron pairs in maintaining the octet rule in non-metals, highlighting the importance of covalent bonds in forming stable molecular structures in various chemical compounds.
