Before the scientific revolution which elements were known that were developed by Aristotle?
Earth
Fire
Water
Air
Carbon
Who coined the term "Atomos"
Democritus
Mayer
JJ Tomson
Dalton
What did Democritus say?
Small particles that could not be created or destroyed made up everything
Created 5 postulates including one that said everything was made of indivisible atoms
Said that part of the atom was negative and discovered the electron using cathode rays
Said part of the atom was positive and discovered the proton by shooting rays at gold
What did Mendeleev and Meyer do?
Arranged the elements by atomic mass
Discovered the proton
Discovered the electron
Wrote 5 postulates
What patterns did Mendeleev and Meyer notice? (Select all that apply)
Atomic weight increases as you go up the list of elements
There was a pattern to the weight that repeated every 8 elements
Atomic weight decreases as you go up the list of elements
They noticed none of the above
What did Meyer also notice?
Elements behave similarly based on the volume and weight of their atoms.
Part of the atom was positive due to protons
Part of the atom was negative due to electrons
None of the above
What was one of Mendeleev's great accomplishments?
Publishing the periodic table with empty spots he predicted would be discovered
Found out that elements behave similarly based on volume and weight of their atoms
Found the electron by shooting cathode rays
Found the proton by shooting rays at gold and noticing some of them bounced back
What did Henry Moseley do?
Order the elements based on their atomic numbers
Ordered the elements based on the atomic mass
Found the protons by shooting rays at gold
Found the electron by using cathode rays
How did Moseley discover the atomic number of elements?
Using an X- Ray
Using cathode rays
Shooting rays at gold
None of the above
What are valence electrons

High melting points
Consist of most of the elements on the periodic table
What is true about nonmetals?
Most are gases at room temperature
Poor conductors and brittle
Ductile and malleable
Solid nonmetals can be brittle
Which are true about metalloids?
They have properties of both metals and nonmetals
Intermediate number of valence electrons
Shiny or dull with an easily changeable shape
Conductors, but they aren't great conductors
Are ductile and malleable
What does Coulombs Law say?
Opposite charges attract
Atoms are indivisible
Matter is composed of atoms
Atoms of the same element are identical, but atoms of different elements have different properties
