What did you include in your response? Check all that apply. All elements in group 13 have 3 valence electrons. Losing electrons during chemical reactions causes metallic behavior in elements. It is easier to lose 3 electrons than it is to gain 5, so most group 13 elements behave as metals. Having fewer electron shells makes it easier to gain electrons. Boron has so few electron shells that it is just as easy for it to lose electrons as it is to gain electrons, so it behaves like a metalloid.

Which best explains how a heat pump can heat a room? cold air from the house is moved through pipes, where it absorbs thermal energy. warm air from outside is pushed into the house to replace the cold air. combustion warms the air when chemical energy is transferred to thermal energy. fuel is used to move a piston, which pushes warm air into the house.
