A chart that organizes all known elements into a grid of horizontal rows (periods) and vertical columns (groups or families) arranged by increasing atomic number

• Element graph

• Compound chart

• Periodic table

• Newtons Craddle

this is the average mass number across all isotopes of that element 

• Average atomic weight (amw)

• Average atomic mass (amu)

• Nucleus weight

• Newton

The process of a gas changing directly into a solid without turning to a liquid (straight from gas to solid) Ex: moist air from house comes in contact with cold air outside and forms ice crystals on the window

• deposition

• freezing

• sublimation

• condensation

Who was hold the claim to fame for the periodic table

• Jimmy Neutron

• Gregor Mendel

• Dmitri Mendeleev

• James Dalton

The amount of energy required for the liquid at its boiling point to become a gas

• Heat of vaporization

• Melting point

• Boiling point (100 Celsius for water)

• Heat of fusion

The smallest part of an element that retains the properties of that element

• Molecule

• Proton

• Neutron

• Atom

This is the number of protons and neutrons added together

• Mass number

• Atomic number

• Nucleus

• Newton

Mass is how scientists measure how much matter/ particles  are in something.

• Periodic table

• Mass

• Bohr diagram

• Volume

This is any element that has a different number of neutrons

• Molecule

• Valence electron

• Ion

• Isotope

This is the symbol of the element found of the periodic table

• Atomic mass

• Atomic symbol

• Atomic symbol

• Atomic weight
