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
BASIC Atom little area on a board, at the expense of greater height. BASIC Atom "Basic Atom" refers to a line of self-contained microcontrollers from Basic Micro. Like the Basic stamp, the Basic Atom line is based upon various microchips pre-programmed with an interpreter, making it easy to change "programs", as they are only "data" being interpreted. A compiler converts a high level language into the interpretive "code" which is then loaded in as data, and run. Basic Atom chips may be added to other projects via the familiar Dual in-line package style, or the higher density TQFP. One small Basic Atom
