Two.
Sulfur can form a maximum of six bonds in a Lewis structure.
There are two single bonds shared between hydrogen and oxygen in the Lewis structure of ethanol. Each bond consists of one shared pair of electrons.
H2CO. The oxygen will have two pairs of non-bonding electrons
In the Lewis dot structure for a fluorine atom, there should be 1 bond displayed, as fluorine has 1 unpaired electron that can form a single bond with another atom.
Two equivalent Lewis structures are necessary to describe the bonding in PH3. In one structure, phosphorus forms three single bonds with hydrogen atoms, and in the other structure, phosphorus forms one double bond with one hydrogen and two single bonds with the remaining hydrogens to satisfy the octet rule.
Sulfur can form a maximum of six bonds in a Lewis structure.

In the Lewis structure of ethylene glycol, a total of 16 valence electrons need to be shown. There are 6 pairs of electrons that are bonding (forming bonds between O-H, C-O and C-C) and 2 pairs of electrons that are nonbonding (on the oxygen atoms).

The answer is 12. If you draw the lewis dot structure for formaldehyde, you have to remember to draw the non-bonding pairs on the oxygen atom, and when you count all the electrons, remember that the lines used to represent bonds are counted as 2.
For fluorine: 8 dots.
There are two single bonds shared between hydrogen and oxygen in the Lewis structure of ethanol. Each bond consists of one shared pair of electrons.
Three bonds should be drawn in the Lewis dot structure for SO3. Sulfur forms a double bond with one oxygen atom and single bonds with the other two oxygen atoms to complete its octet.
H2CO. The oxygen will have two pairs of non-bonding electrons
In the Lewis dot structure for BH3, there should be 3 bonds drawn. Each hydrogen atom forms a single covalent bond with the boron atom. Boron has three valence electrons, so it can form three bonds with the hydrogen atoms.
