5.02 Chemical bonding Live Lesson

Which of the following is NOT a property of Covalent Bonds

• Low Melting Point

• Share electrons

• Weaker Bonds

• Conductive when dissolved in water

Why does electricity flow through the human body easily.

• The human body contains pure water, which is a covalent bond

• The human body is an insulator and traps the current

• Ions from the ionic compounds we eat, like salt, are found throughout the body in muscle tissue, nerve cells, and blood.

• Sugar, which is covalent, breaks down in the krebs cycle and that is what carries the electricity

Based on the octet rule, how many valence electrons does each element need to become stable? (there are a few exceptions, like hydrogen)

• 2

• 4

• 6

• 8

If you were going to cook spaghetti in boiling water, which compound would you put in the water to speed up the cooking by increasing boiling point?

• Salt (ionic)

• sugar (covalent)

• Nothing, just water
