Energy
A spectrum of electromagnetic energy
What is the electromagnetic spectrum?
The number of protons in an atom. This can also be the number of electrons, but that number can change.
What is the atomic number?
Two or more things combine without a chemical reaction.
What is a mixture?
What is a push or a pull?
What are the laws of nature?
Kinetic Energy
What is energy of motion?
One or two letters.
What is atomic/element symbol?
A group of atoms bonded together.
What is a molecule?
The fundamental forces.
What are gravitational, electromagnetic, strong nuclear, and weak nuclear?
Some kind of underlying principle, an intelligent creator, or none whatsoever.
What are the reasons for the laws of nature?
What is fusion?
Atomic mass
What is the average of all an atom's isotopes?
This has an array.
What is a crystal?
Why does nothing ever really touch?
The transparency of this allows the Earth to trap just enough heat for life and for us to see out into space.
This type of potential energy is found in the bonds of molecules.
What is chemical potential energy?
This represents a compound; it includes the symbols of all elements present and how many of each are there.
What is a chemical formula?
A homogenous mixture
What is a solution?
What is a field?
This, which is created by Earth's iron core, provides us with a magnetosphere that protects the Earth from solar wind.
What is the magnetic field?
What is mass?
When these are present in a chemical formula, we only multiply what is inside.
What are parentheses?
These all have the same number of protons in their nucleus.
What are elements?
Every object with mass exerts a gravitational force on everything else with mass.
What is the Law of Universal Gravitation?
If these were slightly different the physics and chemistry that make life possible would change completely.
What are constants?
