Atom Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons. Protons and neutrons are called nucleons. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, that atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative
Atom (system on chip) 2011, Intel announced an accelerated roadmap for Atom SoC. The 22 nm Silvermont microarchitecture was scheduled for 2013 release, and release of the 14 nm Airmont microarchitecture was scheduled for 2014. It has been reported that Silvermont-based Atom SoCs will be codenamed Tangier (Merrifield smartphones), Valleyview (Bay Trail tablets), will be available in single-, dual- and quad-core versions, and Valleyview will include Intel's 7th generation GPU, allowing for 4–7× improvement over existing Atom GPUs. Other upcoming Silvermont-based Atom SoCs include Rangeley and Avoton (part of Edisonville platform). Airmont-based Atom platforms will be codenamed Moorefield (smartphones) and Cherry Trail (tablets) using
