What are Metals?
Metals are a class of elements that typically share these properties:
* Lustrous: They have a shiny appearance.
* Malleable: They can be hammered or pressed into different shapes without breaking.
* Ductile: They can be drawn into wires.
* Good Conductors: They conduct heat and electricity well.
* Solid at Room Temperature: (Except for mercury, which is a liquid)
* Reactive: They tend to lose electrons easily, forming positive ions.
Common Examples of Metals:
* Alkali Metals: (Group 1) Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), Francium (Fr)
* Alkaline Earth Metals: (Group 2) Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), Radium (Ra)
* Transition Metals: A large group in the middle of the periodic table, including Iron (Fe), Copper (Cu), Gold (Au), Silver (Ag), Nickel (Ni), and many more.
* Other Metals: Aluminum (Al), Tin (Sn), Lead (Pb), Zinc (Zn), Mercury (Hg)
Important Notes:
* Metalloids: Elements like silicon (Si) and germanium (Ge) exhibit properties of both metals and nonmetals, making them "metalloids."
* Not All Elements Are Metals: Nonmetals like oxygen (O), nitrogen (N), and chlorine (Cl) have different characteristics.
