Covalent Bond
🧬
COVALENT BONDING
generally occur between elements near each other on the periodic table.
The majority coming from nonmetallic elements.
STABILITY ⚖️
The octet rule
Complete octet rule results in stable noble-gas configuration.
Can be achieved by gaining or loosing valence electrons as well as sharing them.
A
molecule
is formed when two or more atoms bond covalently.
COVALENT BOND FORMATION ⎈
Diatomic molecules of the same element exist this way because is more stable.
If there is an atom with 7 valence electrons and two fluorine atoms approach each other, forces will be implied. Net attraction would be on its maximum and both would be complete now.
The most stable covalent arrangements is with some optimal distance between nuclei.
SIGMA BONDS
🧫
When the pair of shared electrons is centered between the atoms.
The orbitals are overlapped.
Can be formed when an s orbital overlaps with another s or p orbital, or two p orbitals overlap en-to-end.
SINGLE COVALENT BONDS
⦿
When only one pair of electrons is shared.
The molecule is more stable than either atoms by themselves.
Depending on the group is the number of covalent bonds they can have. Group 17-1, group 16-2, group 15- and group 14-4.
As well as in some cases forming with identical atoms.
