Vocabulary atoms and elements
| Term | Definition |
|---|---|
| matter | anything that has mass and takes up space. |
| mass | the material that matter is made up of. |
| space/volume | the specific area/place that matter takes up. |
| density | d=m/v the amount of mass in a specific volume of space. |
| atom | smallest part of an element,the building blocks of all matter. |
| proton | particle of an atom with a positive charge located inside the nucleus. |
| electron | particle of an atom with a negative charge, it moves around the nucleus and has an attractive force that allows it to bond with other atoms. |
| neutron | particle of an atom with a neutral/no charge located inside the nucleus along with the proton. |
| periodic table | large grid that identifies and classifies all of the elements by their chemical and physical properties. |
| element | the simplest substances that cannot be broken down/ they make up all matter in the universe. |
| periods/rows | rows that tell how many energy levels each elements has for the electrons to move around |
| groups or family/columns | columns that tell how many valence electrons have. |
| valence electrons | the electron that move on the outter shell. |
| atomic number | how many protons an element has inside the neclues. |
| 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 substances |
| physical property | the appear and state of matter of a substance |
| ionic bond | when elements either loose or gain an electron |
| covenant bond | the process of elements sharing electrons during bonding. |
| chemical change/reaction | when elements bond together from the attractive force of electrons,creating a new object/substance |
| compound/molecule | objects mixed to turn into a whole new substance,chemically combined. |
| mixture | objects that are mixed together but not chemically changed. ex: a salad |
| Nobel gases | |
| Halogens | |
| Alkali Metals | |
| Metalloids |
