Periodic Table
Term | Definition |
---|---|
Matter | Everything that has mass |
Mass | the material that matter is made up of |
volume | How much room /space matter takes up |
Density | D=m/v the amount of material/stuff matter takes up with in a specific space |
atom | smallest part of an element, the building blocks of all matter |
electron | particle of an atom that surrounds the nucleus,it has a negative charge and an attractive force to bind with other atoms creating everything in the universe |
proton | Particle of an atom with a positive charge located inside the nucleus |
Neutron | Particle of an atom with neutral/no charge located inside the nucleus along with the proton |
Periodic Table | A large grid that identifies and classifies all elements by their chemical and physical properties |
Element | The simplest substances that can not be broken down / they make up all matter in the universe. |
Periods/Rows | Rows that tell how many energy levels each element has for the electrons to move around. |
Groups or families/columns | Columns that tell how many valence electrons each element has/ the number of electrons that can move on its outer shell. |
valence electrons | the electrons that move on the outer shell/ energy level of an atom |
atomic number | how many protons an element has inside the nucleus/ usually is the same number of neutrons and electrons |
atomic mass | the measurement of the mass for an element |
