An electric lamp creates light by forcing electrons through the filament of its light bulb. the kinetic energy of the moving electrons comes directly from? electric kinetic energy. electric potential energy. chemical potential energy. thermal kinetic energy.

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.

What is part of a line has one endpoint and continues in one direction?

You can melt ice by applying pressure because the solid/liquid line has a slope.
