Document Summary

Matter: anything that has mass and takes up space. Element: pure chemical substance consisting of a single type of atom. Atom: a basic unit of matter that consist of a dense central nucleus surrounded by a cloud of negatively charged electrons. Building blocks of matter. atomic number: number of protons found in the nucleus, and the number of electrons atomic mass: total number of neutrons. Mass: a measure of the amount of matter in an object. Density: how tightly packed the matter in a substance is. It is ratio that compares the mass of an object to its volume. Electron: a negatively charged particle that is found outside the nucleus of an atom. atomic nucleus: an atom"s dense central core, containing protons and neutrons subatomic particle: particles smaller than atoms. Isotope: an atom with the same number of protons and a different number of neutrons from other atoms of the same element. stable isotope: atoms which do not breakdown spontaneously.
