Sample flash cards in this set:
|Density||the amount of matter in one unit of volume.|
|Atoms||tiny particles that make up matter|
|Nucleus||tiny, extremely dense core of an atom|
|Electrons||tiny particles in an atom that circle the nucleus at a tremendous speed.|
|Neutrons||-one of the two kinds of particles that make up the nucleus of an atom - has a neutral charge|
|Protons||- one of the two kinds of particles that make up the nucleus of an atom. - positive charge|
|Neutral||lacking an electrical charge|
|Shell||a set of electrons in an atom that orbit the nucleus at roughly the same distance|
|Atomic Number||the number of protons in an atom|
|Element||a substance that is composed of only one type of atom.|
|Compound||a substance that is composed of more than one type of atom bonded together.|
|Metals||Elements located on - the left and center in the periodic table - most are silvery in color - most are solid at room temperature|
|Nonmetal||- located at the right side of the periodic table. - many solids and several gases|
|Periodic Table of Elements||a chart constructed by Dmitri Mendeleev to arrange the elements in such a way as to group similar elements together.|
|Halogen||- Elements next to the last column of the periodic table. - shows a tendency to form compounds with alkali and alkaline earth metals.|
|Sublime||to turn from a solid into a gas|
|Noble Gases||- elements in the last column of the periodic table - gases - do not combine with other elements except under very unusual circumstances.|
|Molecule||tiny group of two or more atoms that are bonded tightly together.|
|Crystal||a geometric arrangement of atoms|
|Ionic Compound||a compound composed of charged atoms or groups of atoms.|
|Chemical reaction||When atoms of elements or compounds are rearranged to form new substances|
|Combustion||- burning - a chemical reaction in which a substance reacts rapidly with oxygen|
