Lewis Structure

Covalent bond is

• when metals lose electron and becomes positive

• non metals coming together to share electrons

• non metals gain electron

Ionic bond is

• when an atom donates electrons to another atom

• sharing of electrons

• when valence electrons are not fulfilled

• hydrogens give electrons to electronegative atoms

To draw the lewis structure for molecules...

• count the total electrons of atoms

• count the valence electrons of the atoms

• count all the bonds of the atoms

• count all the charges and add them up
