Metal

In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic Bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of Elements as distinguished by their ionization and bonding properties, along with the metalloids and nonmetals. On the periodic table, a diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals. Most elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals. A modern definition of metals is that they have overlapping conduction bands and valence bands in their electronic structure. This definition opens up the category for metallic polymers and other organic metals, which have been made by researchers and employed in high-tech devices. These synthetic materials often have the characteristic silvery-grey reflectiveness of elemental metals. The traditional definition focuses on the bulk properties of metals. They tend to be lustrous, ductile, malleable, and good Conductors of electricity, while nonmetals are generally brittle (for solid nonmetals), lack lustre, and are insulators.

In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to Polonium (Po), atomic number 84. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals. These metals have properties that you normally associate with the metals you encounter in everyday life:

They are solid (with the exception of mercury, Hg, a liquid).
They are shiny, good conductors of electricity and heat.
They are ductile(they can be drawn into thin wires).
They are malleable(they can be easily hammered into very thin sheets).

All these metals tend to lose electrons easily. The following figure shows the metals.

Metal is a broad genre of rock music that began in the late 1960s and early 1970s, with roots in blues rock, psychedelic rock, and garage rock. Metal bands typically use distorted guitars, bass guitars, and drums, and often feature a strong rhythm section and loud, aggressive vocals. The genre has been highly influential on popular music, and has spawned many subgenres, including heavy metal, thrash metal, death metal, black metal, and nu metal.

Metal is often seen as a rebellious and anti-establishment genre, and its lyrics often deal with social and political issues. The genre has also been criticized for its violent and misogynistic imagery, but its fans argue that this is simply a reflection of the real world.

Despite its critics, metal remains a popular genre of music, with millions of fans around the world. It has also been highly successful commercially, with some of the biggest-selling bands in history being metal bands.

Here is a brief overview of some of the most popular subgenres of metal:

Heavy metal: The earliest form of metal, heavy metal is characterized by its distorted guitars, driving rhythms, and powerful vocals. Bands like Led Zeppelin, Black Sabbath, and Deep Purple are considered to be pioneers of heavy metal.
Thrash metal: A more aggressive and extreme form of metal, thrash metal is characterized by its fast tempos, complex song structures, and technical musicianship. Bands like Metallica, Slayer, and Megadeth are considered to be pioneers of thrash metal.
Death metal: An even more extreme form of metal, death metal is characterized by its guttural vocals, fast tempos, and complex song structures. Bands like Cannibal Corpse, Death, and Morbid Angel are considered to be pioneers of death metal.
Black metal: A dark and atmospheric form of metal, black metal is characterized by its fast tempos, tremolo picking, and shrieking vocals. Bands like Mayhem, Darkthrone, and Emperor are considered to be pioneers of black metal.
Nu metal: A more modern form of metal, nu metal is characterized by its heavy use of synthesizers, rapping vocals, and downtuned guitars. Bands like Korn, Limp Bizkit, and Slipknot are considered to be pioneers of nu metal.

Metal is a diverse and ever-evolving genre, and there are many other subgenres that could be discussed. However, these are some of the most popular and influential subgenres of metal.

Metal is a genre of music that is often misunderstood and misrepresented. However, it is a genre with a rich history and a wide variety of subgenres. Metal is a genre that is constantly evolving, and there is something for everyone to enjoy.
