3. Review the results of the previous activity, repeating the distinction between heat energy and temperature. Explain that the metal bar used in the previous activity did not hold heat very well but transferred the heat very quickly; in other words, the metal was an excellent conductor of heat but did not have the capacity to hold or store heat.

Jewelry | Encyclopedia

Jewelry is often associated with treasure—gold, gemstones, valuable materials—and is considered to be objects of intrinsic beauty, though the early beginnings were very different. In prehistoric times, long before humans worked metals, jewelry was made of non-precious materials. Burials of 30,000 b.c.e. in Europe show that at the time ...

radioactivity | Definition, Types, Applications, & Facts

radioactivity, property exhibited by certain types of matter of emitting energy and subatomic particles spontaneously. It is, in essence, an attribute of individual atomic nuclei. An unstable nucleus will decompose spontaneously, or decay, into a more stable configuration but will do so only in a few specific ways by emitting certain particles or certain forms of electromagnetic energy.

A transfer of electrons from a metal to a non-metal results in an ionic bond. ionic bonding Metals and non-metals can react together because the electrons lost by the metals can be taken up by the more electronegative non-metals. This transfer of electrons results in an ionic bond between the metal cations and the nonmetal anions.
