Here are the answers to your questions:

Question 15: A bond between sodium (Na) and chlorine (Cl) is what type of bond?
Answer: b) ionic
(Sodium (Na) donates an electron to chlorine (Cl), resulting in an ionic bond.)

Question 16: Ionic compounds are highly conductive when dissolved in water.
Answer: True
(Ionic compounds dissociate into ions in water, which allows them to conduct electricity.)

Question 17: What two subatomic particles have the greatest mass?
Answer: c) protons and neutrons
(Protons and neutrons have much greater mass compared to electrons.)

Question 19: Which pair of elements listed below would NOT form a covalent bond?
Answer: a) K and Cl
(Potassium (K) is a metal and tends to form ionic bonds with nonmetals like chlorine (Cl), rather than covalent bonds.)
