What is energy
the ability to make something move/ work
name the six types of energy
chemical, nuclear, electric, mechanical, solar, radiant,
sound
what are the three parts of the atom
neutrons, protons, electrons
what is on the periodic table
elements
what is a physical property
one you could see, hear, taste, touch or smell
What are the two types of energy?
potential and kinetic
what makes nuclear energy
the splitting of an atom
what charge does an electron have
negative
what is an element
a pure substance (gold)
what is a chemical property
how it reacts with others
what is kinetic energy
the energy of motion
how is electricity made
by the movement of electrons
what is inside the nuclear
proton and neutron
what is a synthetic element
one man made and not found in nature
how can you tell a chemical change has taken place
odor, bubbles, heat
what is potential energy
energy that is stored
what is mechanical energy
the energy from things moving (like a car)
where do the electrons live?
in the electron cloud

what is the law of the conservation of energy
energy is never lost-it only changes form
