How does heat energy move by convection when a cook heats a pot of water? a. heat energy moves from the air into particles of water that are touching air. b. particles at the bottom of the water carry heat energy to the top of the water. c. heat energy moves from the bottom of the pot into nearby particles of water. d. particles from the water carry heat energy to the particles of air over the water.

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Which of the following are not typically included in the periodic table? a. atomic mass b. element symbol c. isotopes d. number of electrons
