Metals

Definition

Metals are elements that are typically characterized by their ability to conduct electricity and heat, malleability, ductility, and a shiny appearance. They tend to lose electrons and form positive ions in chemical reactions.

5 Must Know Facts For Your Next Test

1. Metals are located on the left side and in the center of the periodic table.
2. They usually have high melting and boiling points.
3. Metals can form alloys with other metals to enhance their properties.
4. Alkali metals (Group 1) are highly reactive, especially with water.
5. Transition metals often form colored compounds due to d-orbital electron transitions.
