Metal - Simple English Wikipedia, the free encyclopedia

2019-4-1 · Most of the properties of metals are due to the fact that the atoms in the metal do not hold onto their electrons very tightly. Each atom is separated from the others by a thin layer of valence electrons. However, some metals are different. An example is the metal sodium. It is soft, melts at a low temperature, and is so light, it floats on water.
