Models and Subatomic Particles
Valence electron shell
What is the outermost electron shell?
This poison, when ingested, causes blindness, decreased level of consciousness, poor coordination, vomiting, abdominal pain, and a specific smell on the breath.
What is wood alcohol?
He developed an atomic philosophy where he stated atoms are indivisible and indestructible.
Who is Democritus?
A different version of the same atom.
What is an isotope?
Protons, neutrons and electrons.
What are the 3 subatomic particles?
The Bohr Model shows where the each of these is plotted in an element.
What are the electrons?
This poison is usually given in small doses to the victim and smells like bitter almonds.
What is arsenic?
His model shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths.
Who is Ernest Rutherford?
This is the reason the mass is different in an isotope.
What is the number of neutrons?
This subatomic particle has a positive charge.
What are protons?
These have positive, negative, and neutral charges respectively.
What are protons, electrons, and neutrons?
This poison is a colorless, sweet smelling liquid that was initially used as an anesthesia by many doctors, but ceased to be used in medical practices because people would suddenly die on the operating table.
What is chloroform?
This chemist created a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun.
Who is Niels Bohr?
In Carbon-14, what the 14 represents.
What is the mass of carbon?
This subatomic particle is neutral and located in the nucleus.
What are neutrons?
In a Lewis Dot Model, these subatomic particles are placed into this shell.
What are electrons in the valence shell?
This chemical was used regularly in the beginning of the 20th century to kill rats in large buildings. It can also kill humans. It produces a tint around the mouth on a corpse.
What is cyanide?
This chemist developed a very simplified representation of the valence shell electrons in a molecule.
Who is Gilbert Newton Lewis?
How you calculate neutrons.
What is mass - atomic number (protons)?
Calculated by adding your protons plus neutrons.
What is atomic mass?
These are used to determine an isotope.
What are neutrons?
This poison, an element on the periodic table, was mixed with gasoline until the 1980s. It accumulates in the brain and can cause "fits and outbursts".
What is lead?
He developed a theory with five principles in which one of them is "All atoms of the same element have the same properties and the same mass".
Who is John Dalton
A different version of the same atom.
What is an isotope?
This tells you the number of energy level an atom has.
What does the period (row) number tell you?
