Division of Periodic Table into s-, p-, d- and f blocks on the Basis of Electronic Configurations. The long form of periodic table can be divided into four main blocks. These are s-, p-, d- and f-blocks. The division of elements into blocks is primarily based upon their electronic configuration as shown in Fig. 6.2.
What is it? The EquiCam is the ultimate piece of filming equipment for equestrian sports, a miniature super light weight camera (just 38g) and two special riding hat camera mounts (elastic hat strap and a hat mount). Film your rides in full 1080p HD for fun and for safety.
The camera is the size of a phone booth and uses 62 separate CCD sensors and a 13-foot light-gathering mirror. After 8 years of construction, the camera was deployed at the Cerro Tololo Inter-American Observatory in Chile to unlock secrets of the universe by photographing broad patches of the night sky.
