The law that says that matter cannot be made or destroyed by ordinary chemical processes.
What is 'Conservation of Mass'?
It is the formula that relates the frequency and the wavelength of light waves.
What is nu = c / lambda?
They were the early forerunners of chemists, and were mostly interested in turning cheap metals into gold
Who were the alchemists?
These parts of an atom have essentially no mass and are negatively charged.
What are electrons?
The process where some atoms' nuclei decompose over time (for example, 14C to 14N).
What is radioactivity?
The height of the crests and depth of the troughs of a wave.
What is a wave's amplitude?

It's the mnemonic for the colors of the visible spectrum
What is ROY G BIV?
He was a Quaker who put forth modern atomic theory.
Who was Dalton?
The number of them in an atom's nucleus determines what kind of atom it is.

This law states that every molecule of water will have the same composition.
What is the 'law of definite proportions'?
It's the class of electromagnetic waves that are just barely too long to be visible.

Who was Lavoisier?
13C has this many neutrons.
What is seven?
Before Rutherford's experiment proved the existence of the nucleus, it was the nickname of the prevailing theory of atomic structure.
