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.
The Lewis dot structure for BCl3 has one boron atom in the center with three chlorine atoms surrounding it. The boron atom donates one electron to each of the three chlorine atoms, resulting in three shared covalent bonds. Each chlorine atom ends up with a full outer shell of 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.

The Lewis structure of Cl2O7 has one central chlorine atom double-bonded to each of the outer oxygen atoms, with single bonds and lone pairs on the other oxygen atoms. The structure also has two double bonds with one oxygen atom at each end of the molecule.
The Lewis structure of BCl4 shows boron in the center with four chlorine atoms attached to it. Each chlorine atom shares one electron with boron, forming four single bonds. This arrangement illustrates that boron has an incomplete octet and forms covalent bonds with chlorine atoms to achieve stability.
Sulfur can form a maximum of six bonds in a Lewis structure.
The Lewis structure of thionyl chloride (SOCl2) consists of one sulfur atom bonded to one oxygen atom and two chlorine atoms. The sulfur atom has a double bond with the oxygen atom and single bonds with the two chlorine atoms.
The molecular structure of BECl is linear, with beryllium at the center and one chlorine atom on each side. In a Lewis structure, beryllium is represented with two valence electrons and each chlorine atom with seven valence electrons. The beryllium atom forms a bond with each chlorine atom, resulting in a total of two bonds and no lone pairs on beryllium.

The Lewis structure for boron dichloride (BCl2) consists of one boron atom in the center bonded to two chlorine atoms. Boron has 3 valence electrons and chlorine has 7 valence electrons, so boron forms 3 single bonds with each chlorine to complete its octet and achieve stability.

For fluorine: 8 dots.
The Lewis dot structure for BCl3 has one boron atom in the center with three chlorine atoms surrounding it. The boron atom donates one electron to each of the three chlorine atoms, resulting in three shared covalent bonds. Each chlorine atom ends up with a full outer shell of electrons.
