physical substance in general, as distinct from mind and spirit. | matter |
a coherent, typically large body of matter with no definite shape | mass |
the amount of space that a substance or object occupies, or that is enclosed within a container | volume |
not hallow or containing spaces or gaps, firm and stable in shape | solid |
having a consistency like that of water or oil, i.e, flowing freely but of constant volume. | liquid |
an airlike fluid substance which expands freely to fill any space available, irrespective of its quantity | gas |
a property used to characterize physical objects | physical property |
a property used to characterize materials in reactions that change their identity | chemical property |
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 |
center of atom that has protons and neutrons(heaviest part of the atom) | nucleus |
positive subatomic particle in the nucleus | proton |
neutral subatomic particle in the nucleus | neutron |
negative subatomic particle that is around the outside of the nucleus | electron |
ability to be flattened into a sheet; bendable | malleability |
ability to be stretched into a wire | ductility |
ability to react with another substance | reactivity |
horizontal rows on periodic table | period |
vertical columns on periodic table | groups |
temperature where solid turns to liquid | melting point |
temperature where liquid turns to gas | boiling point |
shiny, good conductors, malleable, ductility | metal |
like both metal and non-metal, shiny, malleable, semi-conductors | metalloid |
poor conductors, mostly gases, dull | non-metal |
