Iodine Molecular Geometry and Properties

The video tutorial explains how to draw the Lewis structure for iodine (I2). It begins by identifying iodine in the periodic table and calculating the total number of valence electrons. The tutorial then guides viewers through drawing the structure by placing iodine atoms and forming a covalent bond. It ensures the octets are complete and discusses the linear molecular geometry of I2. The video concludes with a brief thank you from Dr. B.

What are the possible physical states of iodine as mentioned in the video?

• Liquid and gas

• Plasma and gas

• Gas and solid

• Solid and liquid

How many valence electrons are there in total for the I2 molecule?

• 7

• 14

• 21

• 28

Why can't the least electronegative atom be placed in the center for I2?

• Because iodine is a noble gas

• Because there is no center with only two atoms

• Because iodine is too electronegative

• Because iodine atoms repel each other

What is the molecular geometry of the I2 molecule?

• Tetrahedral

• Bent

• Trigonal planar

• Linear

How many electrons are shared in the covalent bond between the two iodine atoms?

• 1

• 2

• 3

• 4
