Anything that has mass and takes up space. | matter |
The amount of matter in something. | mass |
The amount of space something occupies. | volume |
Smallest unit of matter. | atom |
Number of protons in an atom of a given element | atomic number |
Number of protons plus the number of neutrons in an atom | atomic mass number |
Center of the atom that has the protons and neutrons (heaviest part of the atom). | nucleus |
Positive subatomic particle in the nucleus. | proton |
Neutral subatomic particle in the nucleus | neutron |

This property describes matter that will shatter if dropped or hammered. | Brittle |
covalent bond | formed when valence electrons are shared between atoms |
covalent bonds | nonmetal bonded to another nonmetal |
ionic bond | formed when valence electrons are transferred from metal to nonmetal |
ionic bond | metal bonds to nonmetal |
chemical bond | force that holds atoms together in a molecule. |
element | matter made up of only one type of atom |
