What electron-dot structures show
Valence electrons of atoms in molecules/compounds
Valence electrons (definition)
Valence electrons (definition)
Electrons in outermost shell of an atom
How to find valence electrons from periodic table
How to find valence electrons from periodic table
Use group number of the element
Noble gas configuration
Noble gas configuration
Full outer electron shells (very stable)
When ionic bonding occurs
When ionic bonding occurs
One atom loses electrons, other gains
When covalent bonding occurs
When covalent bonding occurs
Both atoms want to gain electrons (share)
Key difference: ionic vs covalent
Key difference: ionic vs covalent
Ionic = transfer; Covalent = sharing
Octet rule
Octet rule
Atoms want 8 electrons in outer shell
Balance requirement for ionic compounds
Balance requirement for ionic compounds
Total electrons lost = total electrons gained
Shared electron pairs in structural formula shown as
Shared electron pairs in structural formula shown as
A dash for each shared pair
