Block (periodic table)

A block of the periodic table of elements is a set of adjacent groups. The term appears to have been first used by Charles Janet. The respective highest-energy electrons in each element in a block belong to the same atomic orbital type. Each block is named after its characteristic orbital; thus, the blocks are:

The block names (s, p, d, f and g) are derived from the spectroscopic notation for the associated atomic orbitals: sharp, principal, diffuse and fundamental, and then g which follows f in the alphabet.

The following is the order for filling the "subshell" orbitals, according to the Aufbau principle, which also gives the linear order of the "blocks" (as atomic number increases) in the periodic table:

For discussion of the nature of why the energies of the blocks naturally appear in this order in complex atoms, see atomic orbital and electron configuration.

The "periodic" nature of the filling of orbitals, as well as emergence of the s, p, d and f "blocks" is more obvious, if this order of filling is given in matrix form, with increasing principal quantum numbers starting the new rows ("periods") in the matrix. Then, each subshell (composed of the first two quantum numbers) is repeated as many times as required for each pair of electrons it may contain. The result is a compressed periodic table, with each entry representing two successive elements:

Styles P

David Styles (born November 28, 1974), better known by his stage name, Styles P, is an American rapper, author, and entrepreneur. He is prominently known as a member of Hip Hop group The LOX, founder of D-Block Records and is also a part of the Ruff Ryders hip-hop group, and in addition has released multiple albums and mixtapes as a solo MC. In 2002, he released his debut album A Gangster and a Gentleman. He went on to release Time is Money (2006), Super Gangster (Extraordinary Gentleman) (2007), Master of Ceremonies (2011), The World's Most Hardest MC Project (2012), Float (2013), Phantom and the Ghost (2014), and A Wise Guy and a Wise Guy (2015).

Musical career

Styles P, a member of The LOX and the larger D-Block Hip-Hop collective, grew up in Yonkers, New York rapping alongside Jadakiss (Jason Phillips) and Sheek Louch (Shawn Jacobs). In their late teens the trio met Mary J. Blige who was so impressed with their tough street east coast lyrics, she gave them a big break by putting their demo in the hands of Sean “Diddy” Combs. Diddy immediately hired the trio to write for Bad Boy Records. With the label, The LOX quickly started collaborating on hits with Diddy, the Notorious B.I.G., Mary J. Blige, and Mariah Carey which gave them instant notoriety and status within the hip-hop and mainstream charts.

The Lox

The Lox (stylized The LOX or The L.O.X.) is an American hip hop group formed in 1994, from Yonkers, New York. The group is composed of East Coast rappers Sheek Louch, Styles P and Jadakiss. They had originally signed to Sean Combs' Bad Boy Records in 1995, before joining Ruff Ryders Entertainment in 1999, and have since launched their own label, D-Block Records.

History

Formation and career beginnings (1994–1996)

Jason "Jadakiss" Phillips, David "Styles P" Styles, and Sean "Sheek Louch" Jacobs, began their musical careers in their hometown of Yonkers, New York. As high school students they formed a group called "The Bomb Squad" and began performing at local shows and producing their own demos. In 1994 they appeared on Main Source's "Set It Off" from the album Fuck What You Think. While the local rap scene was being dominated by artists like Raw Rome, Lord Devon and a young DMX, the group began to gain attention for their lyrical style and ability to present tales of urban life. The group eventually changed their name to "The Warlocks" and continued developing a fan base by appearing on underground mixtapes. One of their admirers was the "Queen of Hip hop soul," fellow Yonkers native Mary J. Blige. Mary passed their demo tape on to Bad Boy CEO Sean "Puffy" Combs who signed them to a deal. At the behest of Combs, The Warlocks would later change their name to "The L.O.X" which stands for Living Off eXperience.

Music video

A music video or song video is a short film integrating a song and imagery, produced for promotional or artistic purposes. Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie in marketing campaigns that allow them to become more than just a song. Tie ins and merchandising could be used in toys are marketing campaigns for food and other products. Although the origins of music videos date back to musical short films that first appeared in the 1920s, they came into prominence in the 1980s when MTV based their format around the medium. Prior to the 1980s, these works were described by various terms including "illustrated song", "filmed insert", "promotional (promo) film", "promotional clip", "promotional video", "song video", "song clip" or "film clip". Since the creation and increased popularity of YouTube, mainstream artists now promote new music videos by releasing trailers of short promos on the site for their upcoming song and music video. Consequentially, YouTube has been converted into a social media platform for celebrities and artists to market themselves to their fans and audiences.
