Peridic Table


MATTER anything that takes up space and has mass
MASS the material that matter i made up of
VOLUME how much room/space matter takes up
DENSITY the amount of mass in a specific volume of space
ATOM particle of a atom with a negative charge, moves around the nucleus and has an attractive force that allows it to bond
PROTON particle of an atom with a positive charge located inside the nucleus
NEUTRON particle of an atom with a neutral/ no change located inside the nucleus along with the proton
PERIODIC TABLE large grid that identifies and classifies all of the elements into groups and columns
ELEMENTS the simplest substance that cannot be broken down
PERIODS/ROWS rows that tell how many energy levels each elements has for the electrons to move alone
GROUPS OR FAMILY / COLUMNS columns that tell how many valence electrons each has / the number of electrons that can move on its outer shell / energy level
VALENCE ELECTRONS the electrons that move on the outer shell / energy levels of an atom
ATOMIC NUMBER how many protons an element has inside the nucleus / usually is the same # of neutrons and electrons
ATOMIC MASS the measurement of the mass for an elements atoms
CHEMICAL PROPERTY the ability of substances to combine with one another forming new and different compounds and molecules
PHYSICAL PROPERTY the state of matter and appearance of a substance
IONIC BOND when elements either lose or gain an electron during bonding
COVALENT BOND when elements share electrons during bonding
CHEMICAL CHANGE / REACTION elements bond together through the attractive force of electrons creating some type of reaction and change
COMPOUND / MOLECULE two or more elements combined together in a specific ratio / pattern creating a whole, new and different substance
MIXTURE two or more substances combined together keeping their original properties, the do NOT change in to a new substance / compound
NOBEL GASES all of the elements in group 18 they are most stable elements because they have eight electrons in their outer shell
HALOGENS all of the elements in group 17 they are very reactive bonding easily with elements in group 1 because they have 7 valence electrons and want to be stable
ALKALI METALS all of the elements in group1 they very reactive because they have only one valence electron
METALLOIDS elements between metals and non-metals that can react either way, they have 3-7 valence electrons
ENDOTHERMIC is a chemical reaction that takes in energy
EXOTHERMIC energy is released
