Covalent Bonding R

Put the steps for drawing a Lewis dot structure in order

• Check that the remaining electrons satisfy the octets and add them as lone pairs (dots)

• Add up the total valence electrons of all the atoms in the compound

• Arrange the atoms with more bonding places in the middle

• Connect atoms with bonds (draw a line)

• Subtract 2 electrons for each bond from your valence electrons

How many valence electrons are most stable for an element in a compound (except hydrogen)?
