Neodymium is a chemical element that has the symbol Nd on the periodic table. It has the atomic number 60 which means it has 60 protons in an atom. Neodymium can be combined with other elements like iron and boron to create the very strong neodymium magnet, these magnets can lift up to 1000 times their own weight. Neodymium is a metal that forms a coating of oxide around itself when it is placed in air. It is usually used as neodymium magnets for hard disk drives.
Though neodymium is called a rare earth metal, it is quite common, as common as nickel, cobalt or copper. Like every metal, neodymium is very shiny. It is a solid that melts at 1,024 degrees Celsius, or 1,875 degrees Fahrenheit. Neodymium is in a group of other elements called lanthanides, which are like each other in how they behave. When neodymium is dropped into water, it slowly changes into neodymium hydroxide, if the water or the neodymium itself is hot enough, the change is much faster, and the neodymium may explode. In the air, if the neodymium is hot enough, it can catch fire. Like every other metal, neodymium usually wants to get rid of its electrons, so the compounds it forms are usually with elements that want electrons, as oxygen does.
The neodymium magnets used to make hard disk drives do not weaken over time: they are permanent magnets. They can also be used in microphones or speakers. Electric guitars may use these magnets inside their pickups.
Samarium
Samarium is a chemical element that has the symbol Sm on the periodic table. It has the atomic number 62 which means it has 62 protons in an atom.
Neptunium
Neptunium is a chemical element that has the symbol Np on the periodic table. It has the atomic number 93 which means it has 93 protons and electrons in its atoms. It is named after the planet Neptune in the same way as Uranium is named after the planet Uranus.
Neptunium was discovered in the year of 1940 by two men named Edwin McMillan and Phillip H. Abelson at Berkeley Radiation Center of the University of California. Neptunium is a silvery- metallic element and is radioactive. Its melting point is 637 degrees Celsius and it's boiling point is 4000 degrees Celsius. Its atomic mass is 237 u.
List of WWE pay-per-view events
This is a chronological list of pay-per-views promoted by World Wrestling Entertainment (WWE). Each month, WWE holds one or two annual pay-per-view events. One event is usually three hours long and features six to twelve matches. Pay-per-view events are a big part of how the WWE earns money.
In the table below, NXT TakeOver: Toronto and NXT TakeOver: Brooklyn are marked with asterixes. This is because this will be the third event in the NXT TakeOver: Brooklyn series which is a branch of the NXT TakeOver series. The table also includes WWE Network events.
Many people believe wrongly that the first WWE, then known as the World Wrestling Federation (WWF), pay-per-view was November 1985's The Wrestling Classic. This was a tournament held at the Rosemont Horizon near Chicago. The first WrestleMania event, in March of the same year, was on pay-per-view in some areas. The first two WrestleManias earned much money. After WrestleMania III became one of the best events in wrestling history, the WWF then decided to have more pay-per-views.
The first Survivor Series event took place on November 29 1987. It was shown at the same time as NWA's Starrcade which was thought to be the biggest yearly event for NWA. The WWF informed cable companies that if they were showing Starrcade, they would not be allowed to show future WWF events. Most companies showed Survivor Series. Because of this, Starrcade did not make much money that year. This is thought to be the start of many problems for Jim Crockett Promotions.
The first Royal Rumble in January 1988 was shown on the USA Network. It had the highest rating in the network's history up until that time. The event became a pay-per-view the next year.
The first SummerSlam was held in Madison Square Garden in August 1988. These four events - the Royal Rumble in January, WrestleMania in March or April, SummerSlam in August, and Survivor Series in November - were the only annual pay-per-view offerings (other than the King of the Ring) from the WWF until 1995. After World Championship Wrestling (WCW) started showing more pay-per-views, the WWF increased the number of pay-per-views it showed. At first, the WWF used the name In Your House for its new shows. Beginning in 1996, it began using other names along with the In Your House name (such as Bad Blood and No Way Out). This was done to avoid confusion. By the end of February of 1999, the In Your House name was no longer used.
Both companies increased the number of pay-per-views until they each had one pay-per-view event each month. From the late '90s until 2003, World Wrestling Entertainment had a once-a-month pay-per-view schedule. The pay-per-view events in the United States can be bought through iN DEMAND, Dish Network or DirecTV.
Up until 2003, the WWE ran two pay-per-views a year which were only shown in the United Kingdom. After the brand extension, they stopped doing these two events. Instead of the UK events, they did international tours which were taped for television. Currently, WWE has the WrestleMania Revenge tour, after WrestleMania, at the beginning of the year and the Survivor Series tour, at the end of the year, in the UK. Each includes a RAW, SmackDown!, and an ECW taping.
In Australia, WWE's pay-per-views are shown on Main Event. In the United Kingdom and Republic of Ireland, some pay-per-views are shown on Sky Sports 1 and others on Sky Box Office.
Starting with the 2008 Royal Rumble, all WWE pay-per-views were broadcast in High-definition.
In June 2003, WWE decided to only use people from one brand extension for many of its pay-per-views. Only the Royal Rumble, WrestleMania, SummerSlam and Survivor Series events used people from different brands. WrestleMania and The Royal Rumble were the only events with wrestlers from different brands competing against each other. This allowed WWE to show more pay-per-view events, such as Cyber Sunday and The Great American Bash. From late 2005, they decided to change this and matches with people from different brands were shown more often. In March 2007, it said they would stop only using one brand on each pay-per-view. All of its pay-per-views would have matchs from all three brands. The one-brand-only events were:
WWE Backlash
WWE Judgment Day
WWE The Great American Bash
WWE Unforgiven
WWE No Mercy
WWE Cyber Sunday
WWE Armageddon
WWE Fatal 4 Way
WWE No Way Out
Terbium
Terbium is a chemical element that has the symbol Tb on the periodic table. It has the atomic number 65 which means it has 65 protons in an atom. Its compounds fluoresce green in ultraviolet light. The metal can burned in air to form an oxide.
