Shows all known elements in the universe.

• Shows all known elements in the universe.

• Organizes the elements by chemical properties.

The number of protons found in the nucleus of an atom

• The number of protons found in the nucleus of an atom

• Or

• The number of electrons surrounding the nucleus of an atom.

• An abbreviation of the element name.

• The number of protons and neutrons in the nucleus of an atom.

# of PROTONS = ATOMIC NUMBER

• # of PROTONS = ATOMIC NUMBER

• # of ELECTRONS = ATOMIC NUMBER

• # of NEUTRONS =

• Atomic mass number (rounded off) minus the atomic number

METALS are the best conductors of heat.

• METALS are the best conductors of heat.

• This is because the electrons in metals move more freely than in non-metals, allowing the heat energy to travel across the metal.

• For example, when the spoon touches the hot drink, the heat from the drink excites the electrons in the metal, and the electrons transfer the energy from one electron to another, carrying the heat all the way up the spoon quickly.

Metals are good conductors of electricity.

• Metals are good conductors of electricity.

• Copper, silver, and gold are good electrical conductors. In a conductor, electric current can flow freely. Since metals have free electrons, they can carry a charge easily.
