Discovering Atoms
This scientist convinced the scientific world that atoms actually exist with his brilliant work on Brownian motion.
Who is Albert Einstein?
The nucleus of an atom with 10 protons and the nucleus of an atom with 20 protons both pull on their electrons, but this one does so with more force.
What is the nucleus with 20 protons?
An atomic mass unit is 1/4 the mass of an atom of this element.
What is Helium?
Lithium has 3 protons. This is its...
What is Atomic Number?
When a certain mass of anti-matter comes in contact with a larger mass of normal matter, this happens.
What is the mass of antimatter and an equal mass of the normal matter will be converted into energy.
Jenny has a new baby sister. The atoms that make up her new sister were created in this.
What is an ancient star?
It is difficult, if not impossible to take a picture of an atom with light because of these two things.
What are unwanted diffraction and the fact that atoms are smaller than the wavelength of light.
This is the molecular mass of a Carbon Dioxide molecule.
What is 44 amu?
C12H22O11 is the molecular formula for maltose. Jenny ponders this as she drinks her chocolate malt and realizes that there are this many atoms in a molecule of maltose.
What is 45?
Atoms larger than helium have been manufactured in the past using this phenomenon.
What is thermonuclear fusion?
There are about 100 of these that occur naturally, and are composed of just one kind of atom each, and thus are called pure substances.
What are chemical elements?
There are about as many atoms of air in your lungs as there are breaths of air in this.
What is the entire world?
Often called inert gases, the noble gases include these six elements, known for not wanting to react with other elements due to having full outer electron shells.
What are Helium, Neon, Argon, Krypton, Xenon and Radon?
Compared to the size of a Calcium atom, the average size of a Krypton atom would be this.
What is smaller?
George joins a colony ship traveling to a new planet. They land on the planet without realizing it is made of antimatter. George and the entire colony and spaceship are instantly changed to pure energy along with this much of the planet.
What is a mass equal to George and his spaceship and companions?
This early scientist contributed little and possibly nothing to the understanding of atoms, as he thought that earth, wind and fire were elements.
Who was Aristotle?
An Indium atom and a Bismuth atom are traveling at the same speed. This one has more kinetic energy than the other.
What is the Bismuth atom?
A Uranium atom has a mass of 238 amu. A Hydrogen atom has a mass of 1 amu. The one with the larger diameter is...
What is Uranium? It is only slightly larger.
Of the 3 particles that constitute an atom, these two make up the vast majority of its mass and reside in the nucleus and are also called nucleons.
What are protons and neutrons?
Air is not a compound even though it is constituted of different elements. Instead it is this.
What is a mixture?
This early Scientist was the first to try to describe all matter in terms of atoms and their properties.
Who was John Dalton?
This type of force determines the chemical properties of atoms.
What is electrical force?
An Aluminum atom and a Nickel atom have equal kinetic energies. This one must be traveling at a higher speed.
What is the Nickel atom?
Of these 3 elements, Tungsten, Rhenium and Osmium, this one has the greatest electrical charge in its nucleus.
What is Osmium?
Fred says a quark is smaller than a proton. Jane says an electron is smaller than a quark. The individual who is mistaken is...
Who is neither?
