This scientist said that it is a law that the mass before and after a reaction must stay the same.
Antoine Lavoiser
The subatomic particles in the nucleus are made of even smaller particles called these
quarks
Instead of having to write over and over the electric charge of the electron as -1.6 x 10^-19 Coulomb, they much rather write it as this.
1- or -1
Before becoming digital, these used to have 3 different hands that turned around in a circle.
(Analog) Clock
A simple explanation of Hypothesis is this
An Educated Guess
After millennia, this scientist re-ignited the discussion about atoms
John Dalton
This is the smallest of the 3 subatomic particles and cannot be found in the nucleus
Electron
The US uses Fahrenheit to measure temperature, while the rest of the world uses this
Celsius
When making Rock Candy we poured the boiling sugary water in this heat resistance container.
Beaker
Sounds like a vegetable bulb, but these are in fact atoms with extra electrons
Anions
One of the atomic models sounds like a tasty treat. It was proposed by this scientist, whose name sounds like a Spider-Man character.
J.J. Thomson
Scientist are able to discover and study unimaginable things of the universe, but when it comes to naming things they fumble the ball. Like naming this particle with neutral charge.
Neutron
There are about pi x 10^7 of these in a year.
seconds
Cathode Rays
If we combine two ions and obtain a neutral compound, chemists call it this.
Salt
Using alpha particles and a gold sheet, this scientist discovered the proton. What an "earnest" way of doing so.
Ernest Rutherford
Making up most of the weight of the atom, no wonder we call the sum of these two the "mass number"
protons and electrons
The length of an atom is 1 Angstrom, which is 10^-10 (or one ten-billionth) of this.
meters
Atoms are extremely small, impossible to view without a Scanning Tunneling "This". It's kind of a reverse telescope.
(Electronic) Microscope
Deuterium and Tritium are the only named isotopes. They are isotopes of this element.
Hydrogen
Light moves fastest in a vacuum and slows down when in air or water or another medium. When light goes faster than what it should in that medium, a blue glow is radiated. It is named after this Russian scientist.
Pavel Cherenkov
This microscopic cartoon cartoon character created an atomic explosion by tearing something apart "bit by bit, molecule by molecule, atom by atom."
Sheldon J. Plankton
The speed of light is 300,000 km/s or 186,000 mps. Instead of having to write that in their equations, scientists use this lowercase letter.
This instrument has a total of 88 keys, 52 of which white and 36 are black.
(Grand) Piano
This Italian maker from the 17th century is highly regarded as the inventor of the piano.
Bartolomeo Cristofori
