Vocabulary for Matter and Elements

Matter Anything that takes up space and has mass.
Mass The material that matter is made up of.
Volume How much room/space matter takes up space.
Density D=m/v The amount of material/staff matter takes up within a specific space.
Atom Smallest part of an elements, the building blocks of all matter.
Electron A particle of an atom that surrounds the nucleus, it has a negative charge.
Proton A particle of an atom with a positive charge located in the nucleus.
Neutron A particle of an atom with with a neutral NO charge inside the nucleus.
Periodic Table A large grid that identifies and classifies all the the chemical and physical properties.
Elements Is the simplest substances that can not be broken down they make up ALL matter.
Periods/rows Rows that tell how energy levels each elements has the electrons to move around.
Groups/Columns Columns that tell how many electrons each has the number of electrons that move on the outer shell.
Valence Electrons The electrons that move on the outer shell.
Atomic Number How many protons an element has inside the nucleus usually is the same # of neutrons.
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 compound 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 combine together in a specific ratio/ pattern creating a whole and different substance.
Mixture two or more substances combine together keeping their original properties, they do NOT change into a new substance/compound.
Nobel Glass All of the elements in Group#18 they are the most stable elements because they have 8 electrons in their outer shell.
Halogens All of the elements in GROUP #17 they are very reactive because have 7valence electrons and want to stable.
Alkali Metals All of the elements in GROUP #1 they are very reactive because they only 1 valence electron.
Metalloids Elements between metals and non-metals that can react either way, they have 3-7 valence electrons.
