Matter has mass and takes up space. Atoms are basic building blocks of matter, and cannot be chemically subdivided by ordinary means. What's an atom made of? Even though an atom is really small, it is made of even smaller particles. It's basically made of 3 tiny subatomic particles: _______________ ________________ ________________ Parts of an Atom ____(a)_________: in the nucleus (positive) charge 1 amu _____(b)________: in the nucleus o (no) charge 1 amu ______(c)_______: in the electron cloud - (negative) charge o amu The center of an atom is called the_______(d)______ The nucleus contains 2 types of particles: ______(e)_______= positive (+) charge______(f)_______= no charge, neutral This means the nucleus is always positive. The Outside of the Atom: Surrounding the nucleus is a cloud of electrons. ______(g)_______spin quickly. Are negatively (-) charged are very small. Have a mass of O AMU.
