Covalent Bonding in SF6

The video tutorial explores whether sulfur hexafluoride (SF6) is an ionic or covalent compound. It begins by identifying sulfur and fluorine as non-metals on the periodic table, indicating that SF6 is a covalent compound. The video then examines the Lewis structure of SF6, showing sulfur at the center with fluorine atoms surrounding it. The tutorial discusses the difference in electronegativity between sulfur and fluorine, explaining that while there is a difference, it is not enough for sulfur to transfer electrons to fluorine, as in ionic bonds. Instead, they share electrons, forming covalent bonds. The video concludes by affirming that SF6 is a covalent or molecular compound.

What type of elements are sulfur and fluorine in the periodic table?

• Metals

• Non-metals

• Metalloids

• Noble gases

What type of compound is formed when two non-metals combine?

• Ionic compound

• Metallic compound

• Covalent compound

• Alloy

In the Lewis structure of SF6, where is sulfur located?

• At the edge

• In the center

• At the top

• At the bottom

How many fluorine atoms are bonded to sulfur in SF6?

• Four

• Seven

• Six

• Five

What is the role of electronegativity in the bonding of SF6?

• It causes sulfur to lose electrons completely.

• It leads to the sharing of electrons between sulfur and fluorine.

• It results in the formation of an ionic bond.

• It has no effect on the bonding.

What does the line between sulfur and fluorine in the Lewis structure represent?

• A covalent bond

• A hydrogen bond

• An ionic bond

• A metallic bond

Why is SF6 considered a covalent compound?

• Because it involves the sharing of electrons between non-metals.

• Because it forms a crystal lattice.

• Because it conducts electricity in solution.

• Because it contains a metal and a non-metal.
