Period 1 element lithium and fluorine (appearing twice), or left floating above the other elements and not assigned to any group in the periodic table. Helium is almost always placed above neon (which is in the p-block) in the periodic table as a noble gas, although it is occasionally placed above beryllium due to their similar electron configuration. Hydrogen (H) is the chemical element with atomic number 1. At standard temperature and pressure, hydrogen is a colorless, odorless, nonmetallic, tasteless, highly flammable diatomic gas with the molecular formula H. With an atomic mass of 1.00794 amu, hydrogen is the lightest element. Hydrogen is
Power Processing Element Power Processing Element The Power Processing Unit (PPU) is a 64-bit dual threaded in-order Power Architecture microprocessor core designed by IBM for use primarily in the game consoles PlayStation 3 and Xbox 360, but has also found applications in high performance computing in supercomputers such as the record setting IBM Roadrunner. In most instances the PPU is joined by a 512 KB L2 cache to form what is called the Power Processing Element (PPE). The PPU is used as a main CPU core in three different processor designs: The PPU is an In-Order processor, but it has some unique traits
