The nucleus is represented by the atomic symbol for individual elements of valence electrons.
Electrons are represented by dots around the symbol.
There are four orbitals each holding a maximum of electrons. Each orbital gets at least 1 electron before they pair up.
To do a lewis diagram for compounds & ions
1) Determine the # of valence electrons for each atom in the molecule
2) Place atoms so that valence electrons are shared to fill each orbital
Hydrogen has an extra one and chlorine needs one.
They form a covalent bond and share electrons.
Double and triple bonds:
Sometimes the only way covalent compounds can fill all their valence electron levels is if they share more than 1 electron.
