Atomic Models
This was the first person to propose the idea that all matter is made of tiny particles called "atoms."
Who was Democritus?
This subatomic particle has a negative charge.
What is an electron?
The number of neutrons in an atom of Neon-22.
What is 12?
These two Japanese cities are the only cities to ever be attacked with nuclear weapons.
What are Hiroshima and Nagasaki?
A positive ion is formed when an atom ______ an electron.
What is "loses?"
This atomic model features rings of electrons occupying different energy levels.
What is the Bohr Model?
This subatomic particle has a positive charge.
What is a proton?
The number of neutrons in an atom of Oxygen-18.
What is 10?
This type of radioactive decay is when a chunk of the nucleus made of 2 protons and 2 neutrons breaks free.
What is alpha decay?
The bond that forms between a positive and negative ion.
What is an ionic bond?
This atomic model shows electrons in orbits around the nucleus and is what most people think of when asked to picture an atom.
What is the Rutherford Model?
This subatomic particle has a neutral charge.
What is a neutron?
The number of neutrons in an atom of Carbon-17.
What is 11?
This type of radioactive decay is composed only of energy.
What is gamma decay?
The bond that forms between atoms sharing valence electrons.
What are covalent bonds?
This model features an electron cloud, in which electrons exist in a cloud of probable locations.
What is the modern model?
This is the subatomic particle with the lowest mass.
What is an electron?
The number of neutrons in an atom of Americium-241.
What is 146?
This type of radioactive decay happens when a neutron turns into a proton and a high-energy electron, with the electron emitted from the atom.
What is beta decay?
The bond that forms between atoms that share a pool of valence electrons.
What is a metallic bond?
This model is also called the "plum pudding" model, but in class we described it as a chocolate chip cookie, with the positive "cookie dough" filled with negative electron "chocolate chips."
What is the Thomson model?
The atomic number of an element tells us how many ______ there are in the nucleus.
What are protons?
The number of neutrons in an atom of Uranium-239.
What is 147?
A nuclear reactor uses nuclear energy to ____________, which is then used to turn a steam turbine to generate electricity.
What is "boil water?"
When using an electron dot diagram, you can count the number of bonds an atom can form by counting the number of ___________.
What are unpaired valence electrons?
